The Prime-Time Experiment

Riley Lorrent doesn’t do feelings. As a 26-year-old cognitive psychologist, she deals in data, patterns and proof. People, on the other hand, are unpredictable entities she’d rather avoid.


So, when she’s invited to discuss her work on morning show television, Riley expects a polite, controlled conversation.

Instead, she gets Declan Montgomery.

A fitness influencer and personal trainer, Declan is infuriatingly confident and far too accustomed to being right. When their on-air clash spirals into something sharper, he proposes a design a six-month experiment to see whose approach works best. Mind versus body, science versus instinct.

Riley should walk away. Instead, she agrees.

Now forced into close quarters with a man she can’t stand, Riley is pushed beyond controlled variables and neat conclusions. Because this experiment isn’t just testing theories. It’s testing her limits, her patterns and everything she thought she understood about herself.

Declan thinks he can figure her out. Riley knows that’s impossible.

After all, she’s never done an experiment in love… let alone been in one.

Thank you for the ARC!

4.5 🌟

This is one of the most emotionally intelligent books I’ve read. If I hadn’t had a baby, I would have finished it in one sitting. It made me laugh, it made me cry, and it left me thinking long after I’d put it down. I love Leanne 😂👏

The writing was wonderfully immersive. Each POV had such a distinct voice that I always knew whose perspective I was reading. That’s especially impressive for a debut novel.

I also really appreciated the neurodivergent representation. It felt thoughtful and authentic. This isn’t my usual genre, but I found myself completely invested. Please check the trigger warnings before reading, as the story explores some heavy topics.

Overall, this was a fantastic debut novel, and I’m so excited to see where the series goes next. I can’t wait to read Dee and Tyler’s story!

Fun debut by this Aussie author.

Tropes:
Grumpy (her) / sunshine (him)
Spicy neuron rep - really well written
Amazing female friends
Opposites attract

The story is told in third person, which isn’t my preference for writing styles, it wasn’t too bad - especially as I initially thought it was because this was how Riley (FMC) thinks and talks herself.

I will keep my eye out for future stories from Ellie Amos

I received this book as an ARC by the Berry Agency in exchange for an honest review.
I wasn’t expecting this book to absolutely break me. Since it was a gap between what I signed up for this book and actually reading it I didn’t remember the blurb. I just kind of went into a blind. So kind of just thought this is gonna be a fun little book, but instead I was crying. But I would not change it because this week was so good. I loved how Declan changed things for Riley. I also loved Riley and Ebony‘s connection. This book was just really good.

This book is one of my favourite rom coms of the year and congrats to this debut author for smashing it!

This is the story of Riley - an autistic cognitive therapist - and Declan - a personal trainer, and how they accidentally ended up in a bet for 6 months. I absolutely loved these characters. Riley was well written and relatable. Declan was a sweet, funny, total green flag MMC, and their dynamic together was beautiful and funny and had me kicking my feet. There are some heavy, emotional topics in this book that were delivered so well that I felt for these characters but didn’t weigh down the overall story line.

I also loved the supporting characters, especially the best friend Dee, as her relationship with Riley was lovely and sweet and their ride or die dynamic was so clear. I also really liked Declan’s family, his brother, niece, and mother in particular who all welcomed Riley into their lives throughout the bet and who never made her feel different. This book has such a beautiful underlying message of self acceptance and feeling enough, I wish I could read it again for the first time.

If you like: neurodivergent FMC, green flag MMC, reverse grumpy/sunshine, he falls first, found family, this is your book.

Thank you to the author for providing an advanced copy, I loved it so much I have bought the shelf trophy. I am leaving this review voluntarily.

I really enjoyed this! Riley was such a refreshing FMC and I loved getting to read a romance with such thoughtful autism representation. She felt complex and real, and I really appreciated that the story allowed her to be completely herself rather than trying to change who she was.

The dynamic between Riley and Declan was so much fun. I loved the whole science vs fitness experiment premise and watching their initial clashes slowly turn into something more. Their banter was great, but I especially loved the quieter moments where they started to understand each other beyond all of their assumptions.

The friendships were another highlight for me, especially Riley and Dee. The found family element gave the story so much heart and made the characters feel like people you could genuinely know.

There are some heavier themes woven throughout, but I thought they were handled with a lot of care. Overall, such a fun, heartfelt and genuinely refreshing romance with characters I became really attached to.

Definitely one for the STEM girlies, rivals-to-lovers lovers and anyone who loves a romance with a little experiment at its centre.

Amazing autism rep. Really enjoyed the depth of both main characters. It’s so refreshing to read a complex FMC. All the friendships within the story were actually my fav! I really enjoyed the found family element, especially the friendship between Riley and Dee. They feel like real people I’ve known for years.

The book dealt with heavier topics with the utmost care, and almost brought me to tears a few times. The science aspect was thoroughly researched and really well written. I think STEM girlies and Ali Hazelwood lovers will eat this up!

The Prime Time Experiment was an enjoyable read! I loved how Declan and Riley’s connection grew slowly and the slow burn really set the foundation for their relationship. I enjoyed Ellie’s writing style and the overall storyline in this book. Furthermore, the found family and friends in this book also really made it with really memorable characters including Ebony and Dee. It was great to have a neurodivergent FMC. Highly recommend this book and looking forward to the second one!

Thanks to The Berry Agency for this ARC.

ARC review! (But honest)

I got to read this book as an ARC copy, but my review will be honest.

I actually really enjoyed this book, the writing was very very different then I am used to, which was amazing because it fit our FMC perfectly. She was thinking more factually and scientifically, and that was the way she spoke; I loved how that also became clear in the writing style towards us.

I also loved the dynamic between the FMC and MMC and am excited to read the next books in this series!

Would recommend!

The Prime Time Experiment by Ellie Amos | ARC Review

From the very first chapter I was sucked in. I genuinely could not believe this was a debut novel. This is an incredible start for Ellie Amos!

One of my favorite things about this book was getting to experience the world through the FMC Riley’s perspective. It was incredibly interesting to see how someone with Autism thinks, processes situations, and navigates everyday life. Riley’s character was written so well that it was obvious Ellie took the time to create an honest, thoughtful, and respectful representation. Riley is incredibly analytical, direct, and thrives on control. At times her honesty can come across as rude but I absolutely loved that the MMC Declan saw it for what it really was instead of taking offense.

The gym scene near the beginning absolutely had me in tears. While I’m not autistic I do live with bipolar disorder and that scene resonated with me in a completely different way. It reminded me what it feels like when you’re desperately trying to tell someone you’re not okay but they don’t truly hear you. When your own mind feels like it’s working against you and the people around you don’t fully understand what’s happening. That scene hit me much harder than I expected.

The banter between Riley and Declan had me smiling almost immediately. Riley’s assumptions about Declan in the beginning were so entertaining especially knowing what an absolute sweetheart he really is. He is everything I love in a book boyfriend. Kind, patient, thoughtful, funny, and the ultimate golden retriever MMC. Watching their relationship develop was so much fun and absolutely beautiful.

What I loved most about Declan was how deeply he truly saw Riley. He never wanted to change who she was. He simply wanted her to experience happiness and realize that she didn’t always have to carry the weight of being in complete control. He wanted her to feel safe, accepted, and loved exactly as she was. Declan has officially been added to my book boyfriend list. 🥹

Riley completely broke my heart throughout this story. There were so many moments where it physically hurt reading about how difficult everyday life was for her. Watching her struggle to communicate, watching people misunderstand her, and seeing how isolated she often felt had me rooting for her every single chapter.

I also found myself connecting with Riley’s fear that she wasn’t able to be loved and that everyone would eventually leave her. Those thoughts felt incredibly familiar to me. Until I met my husband I genuinely believed those things about myself too. Then I found someone who loves every part of me, the good and the bad, and has never once made me question whether he would stay.

In so many ways I found my husband in Declan.
My husband is my biggest cheerleader, my safe place, the person who puts me first, looks out for me, and loves me exactly as I am even on the days when I struggle to love myself. Reading Declan reminded me so much of him and that made this story even more special to me.

I also adored the supporting characters. Dee is hilarious, unbelievably loyal and such an incredible friend. Her friendship with Riley was beautiful to read about and every interaction between Dee and Tyler had me laughing. Declan’s family also completely stole my heart. The kindness, patience, and understanding they showed Riley was so sweet to read.

I honestly loved everything about this story. The characters felt real, the emotions felt genuine, and Ellie Amos had me smiling one minute and crying the next. It can be difficult reading about a character who struggles in ways that remind you of yourself but it can also be incredibly healing. Riley’s story was heartbreaking, hopeful, and ultimately a beautiful reminder of how resilient people can be.

I am beyond grateful to have received an ARC in exchange for my honest review.

I also desperately need Dee and Tyler’s story… like yesterday. 😅 I cannot wait to get my hands on it!

If you’re looking for a heartfelt romance with great character development, meaningful Autism representation, a golden retriever book boyfriend who will absolutely steal your heart, laugh out loud banter, and a story about finding love, acceptance, and happiness even when you believe you’ll never have it, I highly recommend picking this one up.

Favorite Quote: “I don’t need a version of you that’s easier to love,” he said softly. “I just need you.”

As always please remember that reading is subjective. These are my own thoughts, feelings, and opinions, and they may be different from yours.

Happy reading, lovelies! 😘📚💜

ARC REVIEW - Thank you to Ellie and The Berry Agency for this opportunity!

Rating: 4.5 ⭐️

Be prepared to cry, grab the tissues and a cozy blanket.

What can I say other than wow? This has got to be the most insightful, heartfelt romance I have ever read. Knowing this is Amos’ debut has me VERY excited for what is to come from her in the future.

Characters:
How refreshing is it to have a neurodivergent FMC? Just wow. More importantly though, an FMC that is neurodivergent, strong, independent and an absolute force to be reckoned with. Riley’s character development was something to behold, it felt both genuine and believable. I thought the structure in which she speaks/thinks and how it develops as she starts to heal was beautifully done. A standout moment for me was when she stopped trying to communicate her feelings with factual information and actually placed her emotions in regular feelings that the reader can understand. Riley is absolutely one of my favourite characters ever written. She doesn’t change for the people around her, she doesn’t change for some outside force to drive the plot, she evolves into a version of her that has finally accepted herself and her quirks. Her trauma doesn’t make her weak, her past doesn’t make her a damsel, it drives her strength, showcases her courage and drives home the fact that the only person that needs to accept her is herself. I also loved the development of chapter titles as Riley started to let go of the rigidity and structure she’d been using to mask her fears.

Declan? Well he is just beautiful. I think it is honestly AMAZING the way he was written. He never judges Riley for being different, but rather encourages and supports her individuality. There’s never pressure to be something she’s not, just straight up acceptance. At the end of the day isn’t that what we all want? To just be loved for who we are? He’s a goofy jock type but not in a douchey way. Amos really knows how to write a heartthrob that you want to root for!

Ebony - I don’t want to say anything other than I cannot wait to see more of her in the next story.

Dee is an absolutely wonderful side character. She too accepts Riley for who she’s is and pushes her in a way that is supportive and encouraging. She doesn’t baby or infantilise Riley, instead she encourages her to speak her truth and be herself. I’m very interested in her backstory!

Tyler is tbd for me, I need to learn some more before I make up my mind.


Themes:
Belonging, self acceptance and grief are probably the 3 largest themes I recognised in this book. Riley is on her own journey to accept herself and it is through this she manages to find a sense of belonging. She realises that people who care about you don’t want to hurt you and it’s a massive revelation for her that truly drives the plot and characters forward. The grief is a major aspect I can’t really talk about without spoiling anything but it is beautifully portrayed in this story through multiple characters.

The drawbacks?
My only issue was having 2x of the same neurodivergent representation. I would have liked to see Autism represented in 2 people in different ways to showcase the broad spectrum. There still would have been room for the characters to connect on a baseline level if it was done this way. However, this is merely me nitpicking and having a preference.

⭐ ARC Review: The Prime Time Experiment by Ellie Amos

Rating: ⭐⭐⭐⭐

ARC provided in exchange for an honest review.

I will admit that I struggled a little when I first started The Prime Time Experiment, purely because it is not written in first person, which is normally my preference. It took me a little while to settle into the writing style, but once I did, I became so invested in Riley, Declan and the little family that slowly forms around them.

Riley was easily one of my favourite parts of this book. I really appreciated the way her autism was explained and represented, particularly because we get to see the world through the way she experiences it rather than having it treated as something that needs to be fixed. I also loved what her character meant for Ebony. There was something so special about Ebony having someone like Riley to look up to and seeing an autistic adult who is intelligent, successful, loved and completely herself.

And then there is Declan.

What I loved most about their relationship was not just the chemistry or the banter, although there is plenty of both. It was the fact that Riley feels safe with him. Declan never asks her to become someone else to make things easier for him. He learns her, understands her and gives her the space to simply be Riley.

Knowing what she experienced during her childhood made that hit even harder. Riley has spent so much of her life protecting herself and trying to understand where she fits, and watching her slowly realise that she can be completely herself and still be loved was probably my favourite part of the entire story.

And that love does not only come from Declan.

It comes from Tyler, Dee and Ebony. It comes from Declan's parents. Slowly, almost without Riley realising it, she finds herself surrounded by people who love her without conditions or expectations. The found family feeling in this book absolutely got me. Watching someone who has spent so much of her life without that kind of safety finally discover what it feels like to belong somewhere was incredibly emotional.

Of course, I loved Riley and Declan's romance too. Their whole mind versus body experiment creates such a fun dynamic, and watching their relationship change from arguments and competition into something genuinely tender was so satisfying. Declan is confident and occasionally infuriating, Riley would rather analyse a feeling than actually experience it, and there were definitely moments where I wanted to shake both of them and tell them to JUST TALK TO EACH OTHER.

But by the end, I realised this book was not only telling a love story between Riley and Declan.

It was about love in every facet. Romantic love. Friendship. Familial love. Found family. It was about finally finding people who make you feel safe enough to be completely yourself and discovering that you do not have to earn their love.

I went into The Prime Time Experiment expecting a clever, fun romance about a cognitive psychologist and a personal trainer trying to prove whether the mind or body matters more. I came out of it far more emotional than I expected and completely attached to this little family.

For me, that was what made this book so special. ❤️

This story is a cut above your usual popular contemporary romance story, and it's obvious the author put a lot of thought, love and care into it. In fact I find the synopsis misleading (even though it's technically correct), because reading it you'd expect something much more flashy and shallow. Instead it's a down to earth book populated with nice, emotionally mature people and the story is about the main character's personal growth and self-acceptance, overcoming her trauma and finding love and a family she never had.

Which is why it really pains me to be critical of it, I can see how much love was poured into it, but it is a debut novel and I trust the author will polish her writing and storytelling with time and experience.

The book could have used more polish and tighter editing - there are some errors in the second half, but most importantly it contains way too many repetitions. Certain words and phrases are repeated too many times, there's too much overexplaining everything and overdescribing the same things and details over and over again, very often with the same or very similar wording. One could argue that it's on purpose since the main character is neurodivergent and excruciating detail and repetition are the basis of her worldview and existence. But the novel is not the experimental, postmodern kind, is aimed at a wider audience, and unfortunately those elements make the writing quite tedious at times. Less is more.

My other gripe with the book is that once the element of trauma is introduced, the lines between what is autism and what is her learned compensation for childhood trauma become blurred, and they shouldn't. Especially since Ebony possesses some of the traits, and for Ebony they're autism, for Riley it seems they are results of trauma (or a mix?) and she gets somewhat cured of them.
For that reason I found the trauma part underdeveloped and clumsily integrated.

In my opinion neurodivergence was enough on its own and the addition of became too much. Then we get a love interest whose family has members who are representatives of both neurodivergence and Riley's kind of trauma. That element though I can treat as fantasy and it ended up working within the confines of the story.

I also have to admit that I find it really hard to swallow that a girl with absolutely no support whatsoever went through all of that and managed to be a straight A student all the way. But again, I can treat that as fantasy as well.

Lastly, their bet/dare was public, everything was filmed, Declan is an online celebrity with milions of followers, and with a celebrity brother. One would expect that all of that would play a bigger role instead of being mentioned around 3 times and practically forgotten throughout all of the book.

As I've said it really pains me to be critical because of the obvious love poured into it, but the author has a talent for creating warm stories with lovable characters so I'm sure she'll grow as a writer. And in spite of my criticisms, the story with its themes and characters remains a cut above your typical, shallow romance story.

Summary

Riley is a psychologist who wants every aspect of her life carefully managed. Declan, on the other hand, is a personal trainer and influencer who is determined to shake things up. When an experiment designed to determine whether the brain or the body plays a greater role in overall health brings them together, they have to navigate all the variables, including each other.

---

What I Liked

- The representation was incredibly well done. You can clearly recognize through Riley’s conversations and behavior that she is on the autism spectrum, but she never feels like a caricature.
- I didn’t expect this book to be as emotionally deep as it was. There are so many emotions to unpack, and I really appreciated the emotional maturity of the characters. Romance books often rely on childish misunderstandings or characters refusing to communicate, but that isn’t the case here. The characters are able to take a step back, process what they’re feeling, understand why they feel that way, and consider how best to respond. That made the relationships feel much more realistic and satisfying.

---

What I Didn’t Like

- I needed to know what happened between Tyler and Dee! I’m guessing this will be explored more in Book 2, but I definitely wanted answers.
- The experiment eventually felt a little irrelevant. While it works well as the reason Riley and Declan meet and become involved in each other’s lives, I expected it to play a bigger role throughout the story. We don’t get much about the results, what variables changed after the baseline period, or what the experiment ultimately demonstrated. It is touched on again toward the end, but I felt like that storyline could have been developed more.

My Review

I was not expecting this book to be so wholeheartedly beautiful.

Everything Riley has been through, and the way she continues to grow while also becoming an example for Ebony, was incredibly moving. The family bonds, the friendships, and really all of the relationships throughout this book are so well done.

Even though there is a third-act breakup, it never felt like one of those frustrating romance conflicts where you’re thinking, “This could have been solved with one conversation.” The reasoning behind it made sense, and the resolution felt just as genuine and beautiful as the rest of the story.

I ended up staying up way too late and reading this in one sitting 😬 and honestly, it was completely worth losing the sleep.

---

Would I Recommend This Book?

Yes! Especially if you’re looking for a romance with a healthy, understanding, emotionally intelligent couple who genuinely communicate and try to understand each other.

Thank you to The Berry Agency and Ellie Amos for the opportunity to review an ARC of The Prime-Time Experiment. Before jumping into any story please take care of yourselves and check the author's socials/website for any and all trigger warnings.

This follows Riley (cognitive psychologist) and Declan (fitness influencer/athletic trainer) in a grumpy x sunshine, forced proximity, brains vs brawn romance.

Here is what initially drew me to the book:
- The dynamic between a cognitive psychologist x athletic trainer, given their different fields I was intrigued by how their interactions, communication and banter would be.
- Debut Australian indie author, I love discovering new authors' work!
- The reverse grumpy x sunshine and forced proximity tropes (which have the blueprint to create a story with amazing chemistry, banter and yearning)

Right off the bat the author deserves their flowers because this was such an informative, well researched and unique premise for a romance book. I think the author's ability to write an incredibly complex FMC who is highly intelligent, skilled in her field but very particular and observant, yet at times blissfully unaware, was done very well. Dr Riley Lorent is an extremely unique FMC. I enjoyed how the author was able to explain Riley's nuances such as her issues with room lighting, the aversion to her nickname and not properly identifying the MMC's body language. This all added great depth and insight to the FMC. My heart ached for her when I learnt about the trauma she endured at the hands of her farther and I felt proud when she told Declan. “You weren’t weak, Riles. You were surviving.” Ugh loved that!!

Now onto the things that didn't work for me personally. Whilst this was an incredibly well researched story, using the proper terms in the field of cognitive psychology, it was all a little too much for me. I found myself getting lost and felt removed from the story, and at times it felt like I wasn't even reading a romance book. But that's definitely a personal preference. If you're a STEM lover this will absolutely feed that love of this trope, but it was just a lot for me…and that's okay. I also didn't love the third person perspective. This is only my second book reading from a third person POV and it just does not hit quite the same as a first person POV…again a personal preference.

I actually really liked and enjoyed the friendship between Riley and Dee. I think the author was able to write a really mature and healthy friendship which was the perfect depiction of girlhood. "It was just Dee. Her friend, her safe place. It took her a second to realise that it wasn't their apartment that made her feel safe, it was her friend.”

Overall, I think for a debut novel this was very well done, and whilst this specific story was not my favourite (which is totally okay btw) if you're a STEM lover I think this would be absolutely perfect for you and I definitely recommend it.

From irritation to infatuation, Ellie Amos has brought the Nuro spicy into the work of romance.

The Prime‑Time Experiment is one of those contemporary romances that grabs you by the collar from page one and refuses to let go. Riley Lorrent - the FMC- is prickly and clinical on the surface, while her underlying vulnerability sits just below the surface and is heavily masked along with her other nurodivergant quirks. While burying herself in her work she meets Declan Montgomery - the MMC- the variable Riley can not predict. He’s the annoyingly perceptive fitness influencer who keeps dismantling her emotional firewall brick by brick. Declan is the exact kind of person Riley’s carefully constructed world isn’t built for, but Declan’s determination, patience and quiet care may just be the wrecking ball to take that wall down.

Reading this book I felt as though Riley picked me up and stored me safely in her pocket and gave me a front row seat to witness the way her world crumbled - but for the better. Despite having to wade through that ruble, Rileys world grew 10 fold and watching the chemistry, the banter, the slow burn and the found family that was willing to drag a full grown man down a hall way by his ear for her made by chest feel so full I thought I’d bust.

One of the strongest parts of this story is Declan’s understanding of Riley’s brain. Not in a patronising way, not in a “I’m so emotionally intelligent” way, but in a lived, learned, deeply human way that has been shaped by his relationship with his neurodivergent niece.

*spoiler* Declan’s frustration with himself for not responding fast enough and giving Riley a set of loops, shows how attuned he is to Riley’s sensory needs. It’s subtle, intimate, and beautifully written.

If I had one critique, it’s the best‑friend confrontation. The emotional stakes were high, but the scene felt abit forced and rushed. Like the story didn’t give their history enough space to breathe. It’s the only moment that didn’t land with the same impact and authenticity the rest of the book nails.

And listen… as much as Declan’s brother and Riley’s best friend claim to despise each other, the enemies‑to‑lovers spark is absolutely there. * insert singsong voice here* “I smell a sequel”

Seriously! Their sniping, the disproportionate irritation, the way they orbit each other even when they don’t need to, it’s giving spin‑off energy, and I would read that book in a heartbeat!!!

Overall, The Prime‑Time Experiment is compelling, character‑driven, and emotionally intelligent in a way I have not seen in a romance novel before. It’s messy in the best way, tender where it counts, and full of the kind of chemistry that makes you grin at the page. I thoroughly enjoyed reading this.

Thank you to The Berry Agency for sending me an ARC of The Prime Time Experiment by Ellie Amos in exchange for my honest review. ❤️

What initially drew me to this book was the bright cover and the fact that it was a grumpy x sunshine romance, which I absolutely LOVE, especially when the sunshine character is the MMC and the grumpy one is the FMC. 😂

I kind of remember reading the blurb, but honestly, I went into this one pretty blind, and I think that made me enjoy it even more because I really didn’t know where the story was going.

At the beginning, I was a little confused by our FMC’s POV and the way her thoughts were written. But once I realised that she was neurodivergent, potentially autistic, everything clicked for me. And from that point, I absolutely LOVED her POV.

I honestly haven’t loved a neurodivergent narrative this much since The Good Sister by Sally Hepworth, which gave me a very similar feeling.

I loved getting that insight into our FMC’s brain and seeing how her thoughts and feelings came across on the page. I also really loved watching how those thoughts and feelings changed as her relationship with our MMC developed. It made her character feel so real to me.

And then we have our MMC 🥹

I absolutely loved how open he was to loving our FMC, even though she was a little different from what he might have been used to. He was so patient with her, and I loved how, in those quiet moments when she was struggling in her own head, he knew how to guide and support her without trying to change her.

I also really loved the relationship our FMC developed with our MMC’s niece, who is also neurodivergent. I loved watching them find that common ground and seeing our FMC explain to her dad and uncle that their brains work differently, and that what she might need in a particular moment isn’t necessarily what someone else might need.

Those moments honestly gave the book so much heart.

I actually messaged Ellie when I was only 20% into this book saying that I was absolutely loving it, and that feeling continued all the way to the end. 🥹

This was such a lovely surprise for me. It’s fun and romantic, but it also has so much heart and emotion, and I really loved the way the neurodivergent perspective was woven through the story.

If you’re looking for a fun romance with a LOT of heart, I would definitely recommend picking this one up!

A fantastic debut from Ellie Amos. 💕

A wonderful debut

A classic opposites attract romance with a neurospicy focus - this is The Prime-Time Experiment.

When Riley winds up on morning tv to discuss her research, she is initially okay. Psychology is safe. Research is safe. Infuriating fitness influencer Declan is not safe. After winding up arguing with him on live tv about whose method is better, she somehow finds herself agreeing to a six month research project. Now all she has to do is prove him wrong.

But there are too many variables. Research should be controlled and only change very carefully. That…is not happening here. It turns out Riley is no longer testing her hypothesis - she’s testing her limits. And Declan is more than happy to help push them.

This is such a wonderful debut. It was funny, sensitive, sad and beautiful all at once. I loved being inside Riley’s head and perceiving the world the way she does. Declan turned out to be a super green flag guy who just needed a push in the right direction.

Perhaps my favourite character is Ebony - Declan’s Autistic niece. She and Riley recognise themselves in each other, and it is pivotal to Riley reconciling with her traumatic upbringing.

The romance in this book is a beautiful slow burn. It is spice-free, but the story does discuss Riley’s history of childhood sexual assault. It also deals with death of parents, and the experience of growing up neurodiverse. There is a major scene where we experience overstimulation first hand from Riley’s POV. All of the triggers are approached with great sensitivity.

If you want a new contemporary romance from a debut Aussie author that celebrates neurodiversity, add The Prime-Time Experiment to your TBR.

I was lucky enough to receive an ARC of The Prime Time Experiment & wow… what a debut!

I picked this up expecting a fun slow burn with forced proximity, banter and a 🔥🔥 fitness influencer (ps I got that) but I wasn’t expecting it to become one of the most emotionally intelligent romances I’ve read.

Riley is one of the most unique FMCs I’ve come across in romance. She’s analytical, observant, funny in her own way & genuinely fascinating. Her voice fills a gap in this genre!

One of my fave things about this book is that Author Ellie Amos doesn’t simply introduce Riley to you, she teaches you how to UNDERSTAND her. You start noticing the little things, the way she reads people & the way she moves through the world. Which makes the romance feel so much richer 🥲

This book trusted me to notice the small things & that made every interaction feel so much more meaningful.

I also loved that the female friendships mattered just as much as the romance. Women who truly see each other, back each other & make each other feel safe deserve more page time & TPTE absolutely delivered!!

It’s funny, thoughtful, perceptive and Riley is a character I’ll be thinking about for a long time.

Also… “the shirt has been a functional improvement” is officially one of my FAVE romance quotes (when you know, you know…)

Thank you, Ellie, for trusting your readers enough to peek inside Riley’s brain.

🧠The Prime-Time Experiment by Ellie Amos🧠
🧡ARC FROM AUTHOR🧡
26-year-old Riley Lorrent is a cognitive psychologist; she's comfortable with data, patterns and evidence. People, on the other hand, are emotional and unpredictable. So when she’s invited to discuss her work on a morning TV show, Riley is cautious but expects a controlled conversation. Instead, she gets Declan Montgomery, a fitness influencer and personal trainer. Declan is confident and charismatic, so when their on-air clash spirals, he proposes a six-month experiment to see whose approach works best. Mind versus body, science versus instinct, to which she agrees. Riley quickly realises that this experiment isn’t just testing theories, but her limits and everything she thought she understood about herself. After all, she’s never done an experiment in love… let alone been in one.

OH MY GOODNESS! THIS BOOK WREAKED ME IN THE BEST WAY! First off, thank you to Ellie for sending me this ARC. This book delves into Riley, and through meeting Declan, she has to learn the one thing she doesn't want to: emotions. That said, the BEST thing about this book was, hands down, the connection between Riley and her best friend, Dee. The tears I cried from the 60% mark onwards were enough to fill a river, honestly. The communication, found family and hidden meanings in this book were beautiful. Everything about this book was utter perfection.

I'm so glad this book exists, and I know I'll be re-reading it multiple times and recommending it to others. This was a soothing balm. I felt so regulated reading it, and safe, but also entertained and curious to find out what happened next. I actually feel so attached to the characters now, as if they're my friends, and I want to know what happens next!

Amongst many things I liked about this book, I appreciated the skilful and sensitive depictions of neurodivergence, trauma history, an awesome MMC (which I've never said outside of an Ali Hazelwood review), friendship, found family, accountability and repair after conflict, and self-reflection. I really like how well people communicated (even if not always, they got there when they needed to) and how loose ends were tied up when it came to the things I wanted to know.

I know I'll be returning to this book for years to come, especially when I need a break from stories that just don't "get it".

The combination of thoughtful and intelligent content and reflections as well as fun, lighter scenes and a sprinkling of humour make this book not just comforting, but enjoyable. I didn't have to choose between being understood and being entertained, which I've never felt about any book before.

This book already means a lot to me and I think that anyone would benefit from reading it. Absolutely can't wait to see what Ellie Amos writes next.

I went in curious about the autism representation and came out recommending the book for about four other reasons.

Riley, the female lead, is autistic. She is written as a person, not a teaching moment, and not a collection of traits borrowed from somewhere else. Ellie Amos trusts her to be difficult, funny, and specific, and the book is better for it.

Declan is the part I keep thinking about. His niece is autistic, so he arrives with some experience; he still gets it wrong with Riley. He owns it, and the owning happens on the page rather than off it. That is rarer than it should be. A lot of romance heroes are forgiven in a time skip. This one has to sit in the discomfort and repair it, and watching him do that is most of why the relationship works.

It reads sweet, with minimal on-the-page heat. Worth knowing going in if closed-door is not your thing; it's a 'fit' question, not a fault. For these two characters it is clearly the right choice, and the slow pace is doing the same job. Had the romance moved faster, or resolved differently, I wouldn't have believed it.

Who this is for:
- Readers who want autistic representation written from inside the character rather than from across the room.
- Anyone who likes a slow build where the apology is a scene, not a summary.
- The Kiss Quotient readers who want the same care with far less heat. That was the book this one brought to mind.

Thanks to The Berry Agency for the advance copy. All opinions are my own.

The Prime-Time Experiment by Ellie Amos

◇Debut Australian author◇

The Prime-Time Experiment is a love story for anyone who has held space and loved a neurodiverse person or, had the privilege of being loved in return.

Ellie captures Riley in her all her directness, awkwardness and unfailing loyalty to seeing the world her way.

Declan is a walking green flag and he balances Riley beautifully. His awareness and flexibility allowed Riley the space to grow into and drive their relationship slowly.

The love depctied is not just the burgeoning relationship between Riley and Declan but, Riley loving herself. The characters show vulnerability, adaptation, and articulating their love languages as is right for them.

No spice, no worries. There is enough gentle love to safely shelve The Prime-Time Experiment in the Romance section.

This book bought me to tears early. There is a scene that is perhaps the best first person description of restraint collapse I have read. I could feel Riley holding on, trying to reshape herself until she couldn't. I loved Declan's following chapter when the 'oh shit' realisation of seeing the overwhelm for himself and realising his actions had such a devastating impact on the very human side of Riley.
A brilliant debut and I look forward to the next book in the series.

My thanks to the author, Ellie Amos and The Berry Agency for the eARC to read ahead of publication.

Review of the ARC received:

To be honest, I picked up this book because of the blurb: a neurodivergent FMC, opposites attract, forced proximity, brains vs brawn…but most importantly, a neurodivergent FMC.

What made me stay was the writing.

It was so visually immersive that I felt like every scene was playing out right in front of me. I honestly couldn’t put it down, I ended up reading last 150 pages in one sitting 😀… I think that says everything about how much i enjoyed it.

This book made me smile, laugh, feel giddy and even tear up at times.

What I appreciated most, though, was that it wasn’t just a romance. It also offered a beautiful insight into how a neurodivergent mind experiences the world. Maybe it’s the teacher in me talking, but I found myself thinking about how we can better understand and support neurodivergent people in our everydaylives.

There was also one particular moment where I caught myself thinking — isn’t this exactly what so many women hope to find in their partner? That scene felt so authentic and thoughtfully written.

This is one of those romances that gives you butterflies while also leaving you with something to think about.

Without a doubt, this is a ⭐️⭐️⭐️⭐️⭐️ read and one I’ll happily recommend.

This book surprised me in the best way.

While there is a romance, I didn't come away feeling like this was primarily a love story. To me, this was Riley's story.

Watching Riley navigate the world through the lens of both autism and her past experiences created a deeply emotional reading experience. I am a huge romance lover and it was refreshing to have a story that focused on Riley learning who she is, where she belongs, and how to shape a life that feels like her own.

As the parent of an autistic child, I found Riley's perspective especially moving. Seeing the world through her eyes made me pause more than once and wonder if this is what he sometimes experiences. It offered a perspective that I hadn't thought of.

Declan was another highlight. I appreciated that he never felt like Riley's saviour. Instead, he stood beside her, offering patience, guidance, and the space she needed to grow. Their relationship felt supportive, allowing Riley's personal journey to remain at the centre of the story.

If you're looking for a romance that prioritises character growth, emotional healing, and understanding over extravagant romantic gestures, this is one worth picking up.

What a great book!!!! Think Eleanor Oliphant is Completely Fine and the Love Hypothesis coming together in a neat little package! I absolutely adored it. I don’t think I’ve read many book where a neurodivergent character was written so well, like as if the author knows this character personally! The start of the book was hilarious because of the way Riley thought and her actions. The emotional bits in the middle hit you really hard (check triggers). And Declan, man he is a GREEN forest! I love Declan and Riley so so much! The reverse grumpy sunshine trope is not something I knew I needed!

Also Ebony silently stole the show!

And you know what? I found the lack of spice so so refreshing! Plot heavy, emotional damage and laughs and giggles just the perfect romance book!

Riley is a little different because she perceives people differently, in the utmost logical way. So when she meets hotshot PT Declan in a TV interview, she does the most unexpected thing in order to be proved right. She agrees to perform an experiment with Declan. On national tv!!!!

I genuinely adored this book and I can’t wait to see what she writes next! Thank you Ellie for the ARC of your incredible book 💕💕

ADVANCED READERS COPY REVIEW

The Prime Time Experiment explores the complex emotions surrounding neurodivergence, childhood trauma, self-discovery, and finding someone who accepts you exactly as you are. I fell in love with this story from the very beginning.

I saw so much of myself in Riley. As someone who was diagnosed with ADHD at 29, my own journey has been one of ongoing self-discovery, and there were so many moments throughout this book where I found myself thinking, “YES! That’s exactly what I’ve been trying to say.” Ellie has given words to feelings and experiences that I’ve struggled to articulate myself, and that made Riley’s story feel incredibly personal and relatable.

I loved the dynamics between the characters, particularly Declan’s unwavering acceptance of Riley and the beautiful bond that develops between Riley and Ebony, Declan’s niece. Their relationships brought so much warmth and depth to the story.

The Prime Time Experiment is a beautiful and heartfelt story for anyone who has ever felt like they didn’t quite fit in, or wondered whether they could be truly accepted for exactly who they are. 🧡

Thank you so much to Ellie and The Berry Agency for the opportunity to receive an advanced copy of The Prime Time Experiment. I’m incredibly grateful to have been able to read Riley and Declan’s story early! 🧡

This book really said slow burn and meant SLOW. BURN. 🔥

I’ll admit, there were moments where I was like GIRL… can we please get a wriggle on?! But once it started simmering, I was absolutely invested.

The tension and chemistry were easily my favourite part. It’s that delicious kind of romance where the little moments, the banter and the almosts do so much of the heavy lifting that when things finally start happening, you’ve been waiting long enough that you’re practically yelling FINALLY at the page.

And lines like:
“Set the rules and I promise you I’ll follow them…”
followed by
“I’m good at doing what I’m told.”

EXCUSE ME??? 🫠

I really enjoyed the premise and watching the relationship develop rather than having the romance handed to us immediately. It definitely required some patience through the slower sections, but the payoff made it worth sticking around.

A fun, tension-filled romance for anyone who likes their burn low, slow and eventually VERY hot. 🔥

Received an Advanced Readers Copy for an honest review

“You are capable of love. Don’t be afraid to accept it.” Ellie, you broke my heart and summed up the whole novel in one sentence.

The Prime-Time Experiment is such a raw, heartbreaking novel about letting people into your life and learning that you are valuable just as you are. Ellie gave such justice to her characters Riley and Declan. Declan is so supportive and attentive of Riley from the start, even before he gets to know her on a deeper level. There continuous dynamic and relationship throughout the novel gives you hope for raw and unconditional love.

Riley is such an embodiment of uniqueness and self worth, showing the reader that everyone has value and love to both gove and receive. Thank you Ellie for giving such justice to both your characters and readers!

ELLIE! I WILL READ EVERYTHING YOU PUBLISH 💜🧡
I volunteer to read even your grocery lists! 🙈

✨ The Prime-Time Experiment explores all the elements of a true rom-com: with a seemingly light-hearted rivalry on national television, a blossoming romance wrapped in wholesomeness and unparalleled humour and found family relationships that will last a lifetime.

The themes through this book surrounding neurodivergence, triggers from the past (oh gosh, the tears and heartache I experienced reading Riley’s story) and mental health are written so profoundly and with such grace.

Because in the end, this is truly what matters…
“I don’t need a version of you that’s easier to love… I just need you.” 😭🥹❤️‍🩹✨

Riley found herself. “She had chosen herself. And she had chosen him too.”

THANK YOU, THANK YOU ELLIE!! This story will stay with me forevermore 💜🧡✨
And I can’t wait to read what is to come next for Dee 🌻

PS: Quokka Declan is everything! 😭🥹

I received this book as an ARC reader in exchange for my review!

I really enjoyed this one.
Without giving too much away, I loved the conflict of Declan seeing something he loves about someone else in Riley, and sort of knowing how that makes her tick, and that trait being what attracts him to her.
I also love that when he realised he had assumed certain things of/for her, he kind of realised it in hindsight and knew what he had done wrong.

I love that every character was written so individually. There are two quotes that I really, especially loved:


When you know someone's heart, silence is a comfortable thing.
