The Love Constant

Binary Hearts #3

by Ana D'Arcy

As Andrea refuses to let go of the man she loves, she and Lex discover that love can be just as dangerous as it is powerful, and survival is anything but guaranteed.

——————

Lex’s past has caught up with him, blowing his life apart and stealing the future he dreamed of with Andrea. As he struggles to accept the reality of what he’s lost, a new concern arises: Andrea is determined to get him out, and he knows exactly how far she’s willing to go to make that happen.

Andrea isn’t giving up on their love story. She’s found her person in this universe, and nothing will stop her from getting him back. There’s no future without Lex, so she’ll risk everything she’s built, if that’s what it takes. Rules, dangers, consequences … none of it matters if it means leaving him behind.

What neither of them realizes is that getting Lex out is the easy part. Forces they can’t see are already watching, waiting, and closing in. What started as a fight to reclaim their future turns into a battle for survival—one that will test their trust, their resilience, and the limits of their love.

Their bond has never been stronger, but a love like theirs has a way of making people reckless.

And this time, recklessness might cost them everything.

I enjoyed this series overall. The first two books were excellent. This one fell a bit flat for me unfortunately. Especially from the time Lex was released until the last 25% or so when Lex and Andrea took down the big bad. It could have been about 200 pages shorter and still had all the same stuff happen.

If someone gives me a cute romance trilogy i would run as fast as I can and not look back 😭.
This was large as fuckkkkkk ! And u can’t convince me that sex marathon was normal. THEY FUCKED LIKE THERE’S NO TOMORROW! 50% of the trilogy was pure smut 😭

I can’t believe that’s the end 😭
That bonus chapter had me! Lex and Andrea have been through so much in this one compared to the first two. Their relationship goes to a whole new depth and you just know these two were going to fight to the very end for each other. I also love that Andrea is a badass heroine in this 💪 we don’t get many heroines in the modern day worlds in books and I lived for this. Her noble qualities shine such a light for Lex in this book and it’s admirable. They got the ending they deserved and then some.
As for the story/plot line I loved how complex it was, and how well thought out it was. There was many moments I sat on the edge of my seat thinking ‘oh god, this is it’ bit it was turned around in ways I didn’t see coming and it really kept me gripped the whole way through.
The heat is also something else in this one, it’s much more intense, but still very tasteful and they definitely like to keep it interesting 🤌
All in all I loved it and I’m sad it’s over. Worth the read if you’re looking for a series that is packed with spice but looking for something with some stem vibes, found family feels, geeky references and a whole heap of hero complexes 💪

Fijn om te weten hoe het eindelijk afloopt met deze personages, en het is ook echt een goeie serie, maar jeetje, had ook met gemak met 150 pagina’s minder gekund haha

I was so excited to get an eARC of this book to review. It was one of my most anticipated books for 2026!

And it did NOT disappoint. Ana D’Arcy writes not only some amazing spicy scenes, but the story she has told over these three books has been absolutely phenomenal. A roller coaster ride in the absolutely best way possible.

When we left off with the cliffhanger in book 2, I was so worried about how things were going to unfold. Even knowing it’s a Romance with a guaranteed HEA, I was impatient to figure out how things would get resolved and oh boy was it absolutely epic. We got a little bit of a suspense/thriller in this book, which as so fun, and definitely got my heart racing!

Lex and Andy were as cute as ever, and their love for one another really got to shine in this final installment of the binary hearts trilogy. I cannot recommend this series enough. I loved every moment of it. The only bad part is that it has come to a well deserved, and absolutely beautiful, end.

[kaitlyns_library · Rating 4 out of 5]

What an ending to this trilogy! This was a high stakes book and takes a step back from the workplace romance trope that was in the previous books.

I really loved Andrea in this book and found her to be such a strong FMC, especially in this book.

There was a lot going on in this book, but to me, that wasn’t necessarily a bad thing. What I will flag though is that I thought there were some conversations between the MCs and SCs that seemed too convenient and that there was a lack of consequence (towards the end).

I was on an adventure with this book, and I was strapped in for the entire ride.

3.75✨

It’s usually hard for me to stay invested when a series sticks with the same couple past book two, but this one still pulled me in.

Lex’s back-and-forth had me feeling everything… not always in a good way, but it definitely kept me hooked. And I loved Andrea fully embracing her chaotic, sex-obsessed goblin energy.

The story took a lot of unexpected turns and felt quite different from the first two books, which I both appreciated and struggled with at times. Overall, I have mixed feelings, but I’m still glad I stuck it out for Lex and Andrea’s happy ending.

What a CONCLUSION! The Love Constant is the final book in the Binary Hearts Trilogy. It was suspenseful, dangerous, romantic, and everything in between. And as always, spicy as hell...the make-up slex was *chefs kiss*.

Ana...I'm sorry, but I did end up skipping some pages...I got too stressed out. And just like suspenseful TV shows, I had to look away. AKA skip ahead😂😂

What I loved most about this series was that while the trilogy felt cohesive, each book also hit on such different tropes and problems.
- The Desire Variable - Workplace Romance, Forbidden Love
- The Passion Parameter - Second Chance Romance, Brutal Cliffhanger, Vulnerability, Communication Work
- The Love Constant - Action Packed, Suspense, Badass Andy, Reconnection, Forgiveness

I'm sad that Alex and Andy's story is over, but I can't wait to see what Ana D'Arcy writes up next...🏎️🏎️🏎️

[Andrea Manieri · Rating 2 out of 5]

This was just way too long.

I am all for smut but not when it’s being used to just drag out the book. I really enjoyed the first two books in the trilogy but this one felt like it really went off the rails in terms of unrealistic plots and sex scenes. Then the actual plot ending ended up being a little anticlimactic I think because of all the really long sex scenes breaking it up.

Thank you to Ana D’Arcy for the ARC.

idk if the bonus chapter was just apart of the kickstarter copies, but i hope it is apart of the official release because it was one of my favourite bonus chapter I have ever read. it was the perfect way to complete Alex and Andrea's story ❤️

if you think the first two books in this series is spicy, then just you wait 🤭🤭🔥

[Amanda Silver · Rating 2 out of 5]

I wanted to tear out my eyes by the end of this. Ended up rage reading the last half of it.
I absolutely loved the first book of this series and the second one was meh but this…wtf even was this??
2% of this FIVE HUNDRED page book was interesting plot and the rest was repetitive spicy scenes.

[Marisa BG · Rating 5 out of 5]

Loved this series! These two have chemistry for days!

[AvidReader_ · Rating 1 out of 5]

I don’t think I have ever been more pissed off at a book series before. I DNF’ed at 43%. This book claims to be romance but it is 90% smut with 10% of the lousiest contemporary story telling I’ve read in a long time.

The plot is so convoluted that it is nonsensical. I felt like I was reading the equivalent of those horrible multi-vehicle accidents on the interstate that you can’t look away from. I eventually got to where I couldn’t will myself to continue.

I don’t understand what happened. Was I punk’d? Or perhaps the first book was not as good as I thought.
I adored Up the Ladder and thought this series would be equally as good. Boy, was I wrong.

5⭐️/ 5🌶️

*A HUGE THANK YOU to Ana D’Arcy for providing me an arc of her book! Thank you Ana, you amazing, beautiful soul!

*Check content warnings before reading.

Let me just start off by saying that, Ana D’Arcy has written such an amazing story. Just writing this review I’m feeling so emotional because, Andy and Lex have captured my heart and I love them so much. Over the course of this trilogy, I have seen Andy and Lex go through so many different things together and as individuals. What started out as a boss/employee romance, to one where Andy just wanted to have some fun, and Lex being unable to hold back from the freckled intelligent beauty working at his company, Andy and Lex were endgame from day one. To see how each book within this trilogy had evolved is something special, and goes to show that even romance books have a way of surprising you. Ana D’arcy had me feeling a multitude of emotions while reading this book! From tears of joy, tears of sadness, leaving me gobsmacked, and shocked at the things that occurred, and yet again making me all hot and blushing over Lex and Andy’s spicy times together, there was never a dull moment reading this book.

What can I say other than, this is a certified five star read. Any rating wouldn’t feel fair, as this book made me feel a lot of things, and I was FULLY IN THIS BOOK! Immersed, invested, and at the edge of my seat, yeah Ana’s writing did ALL THAT AND MORE TO ME! I think it’s interesting to see how things changed a lot for Andy and Lex compared to the first book to now the final book. This book took an entirely different turn in terms of what Andy and Lex were up against. If you haven’t read the second book, you’ll have to in order to fully grasp and understand the plot in this book. I think the way Ana wrote this book was unique because, she could have easily stuck to it being just a simple romance, but staying the course that she wrote, she expanded upon a new set of challenges that further pushed Andy and Lex to face something that didn’t anticipate. In addition, with everything that happened in this story, it also tackled the aspects of Lex and Andy’s relationship in how there was still things they needed to work through. Much like any relationship, Andy and Lex had their own hurdles to overcome, but dang…the obstacles they faced ended up being ones that were life and death. I don’t want to say too much over the plot and what occurred in this book because, if you just go in and read it for yourself, I think you’ll be left feeling shocked and downright surprised by what ends up unfolding throughout the book.

Even with everything going on in this book, there was still time of my favorites, Andy and Lex to be together…kind of. The events of the last book still continued in this book so, some parts of the book weren’t exactly the lighthearted fun times I was used to. I found myself feeling worried and anxious for both, Andy and Lex because, with what they had experienced and were dealing with throughout the story was a lot. Through the ups and downs, Andy and Lex managed to communicate and avidly work through issues within their relationship and continue to grow as a couple.

This book had me in its chokehold! There was no stopping me from reading, it got to the point that I only stopped reading to, sleep, eat, and drink. Other than that, I was all about Andy and Lex! For such a highly anticipated read, this book went beyond my expectations. I think readers/ fans of this trilogy are in for a treat of seeing how Lex and Andy navigate the next part of their story. This was by far the longest book in the trilogy I read or at least it felt like it to me, and with the bonus chapter at the end, it was such a long book, but honestly it made up for a satisfying and heartwarming ending to Andy and Lex’s story. I don’t know what else to say other than, I’m sad Lex and Andy’s story is over, but I’m really happy with the way Ana D’Arcy ended this trilogy on a rollercoaster of a wild ride, plenty of romance, new tropes and twists. Highly recommend you read all the books, and anything by Ana D’Arcy is a book you’ll be reading nonstop and an instant fan of.

🌶🌶🌶🌶

What you’ll find in this book:
• Cyber Vigilantes
• Extremely Devoted
• Badass Female Lead
• Door Wide Open
• Latina Nerd x ND Nerds
• Would Die for One Another
• Mortal Danger
• Emotional in Every Way

Soooo the cliffhanger following from The Passion Parameter was the ultimate form of torture, I have been waiting to get my hands on this book and when I say it didn’t dissapoint in the slightest I mean that wholeheartedly. Ana has once again provided a book that feels so intimate and real while also being kind of widely fantastical in its own unique way. The stakes in this book are so dang high, with the risks and lengths that Andy and Lex have to go to being above and beyond what I genuinely thought was possible within the realms of this story but dang did Ana prove me wrong in the most incredible fashion. The relationship between Lex and Andy is not plain sailing and I actually love that, it's stressful to read and even heartbreaking at points but it feels so perfect for them as a couple and their journey to find their version of happiness, how they have to fight eachother to find common ground and understanding and then they have to come together to protect eachother and those that they love. I was captivated by every word, every moment and every glance, I can't believe that it's over but dang was it one hell of a ride.

Looking back on the series, Lex and Andy have come so very far from when we first met them. They have learnt so much about each other during their very messy journey to find themselves and each other, and Ana proves during this story that there are more surprises yet to come. During the course of this story we get to explore Lex and Andy as individual characters as they move through the motions following on from the passion parameter and the consequences of their actions. Having the story be set this way for a period of time means that we get to explore other characters we have met throughout this series, learning a little more about them, their opinions and what motivates them, reinforcing how well rounded Ana has made this world and these characters. To say it is heartbreaking to read as Lex pushes Andy away thinking that is what is best for her while Andy will stop at nothing to help Lex is an understatement. At one point I was actually wondering if we would get the happily ever after I so wanted these characters to have, and Ana kept me guessing with curve ball moments that had my head spinning. I read this book for the tender moments, the heated lust filled situations and those flashes of absolute normalcy inside a story that is wild and pulse pounding.

My favourite part of this story has to be it’s nerdy side, with highly intellectual and skilled coders being such a massive part of the story. Coming from a science background means that I love how these characters can get down and nerdy at the drop of a hat, and seeing how their brain works as they solve problems and sort through emotions. This story peaks and dips with the high stakes situations that the characters find themselves in while they are also busy finding themselves making for a read that you can't look away from in fear of missing one single moment, very much a roller coaster ride. Honestly, the messiness of the romance is something that I am so here for, and I was here for every single page of this series conclusion and devoured it in one single sitting. I would also like to say that the epilogues were absolute perfection, these rounded over the story for these characters in the most beautifully fitting way that had my heart melting. This series has such a special place in my heart, and although I'm gutted that its over, I had the most amazing time being captivated by the words that Ana has written.

Thank you so much to the author for sending me an e-ARC to read and review early.

First Impressions: In the third installment of "Bianary Hearts," Andy (FMC) and Lex (MMC) must face the biggest challenges of their intense, whirlwind romance, and square off against nefarious men to protect themselves and those closest to them.

Pacing: This was a fast-paced, nail-biting romantic adventure. I finished this in two days, because I could not put it down. The passage of time and sequence of events feel fluid and natural. I gripped my seat and my heart raced right until the end.

Character development: I didn't think I couldn't love Andy and Lex more after "The Passion Parameter," but I was wrong. Our MCs grow together in their affection and passions. The reader truly bears witness to their highest highs and lowest lows. Lex, despite his struggles and flaws, learns to relinquish control to the smartest person he knows, and Andy's courage and strength erupts from the page vividly.
The reader also gets to see some real growth from Oli, and my own suspicions from Book Two were confirmed 😉

World Building: The reader travels quite a bit with Andy and Lex, from the misty woods of Canada to the beaches of Belize and beyond to the Big Apple. Each location feels a little magical while also deeply grounded in reality. The reader gets to enjoy the loving, sensual, joyous bubble shared between Andy and Lex. However, there are no punches pulled with the very real world acknowledgements of unchecked power, classism, and the criminal world.

Romance: Andy and Lex have a beautiful romance that emerges from their early struggles. There are very intense scenes featuring arguments and conversations that feel almost too real between them. In the end, however, they succeed through love, compassion, and trust.

Spice: This is by far the spiciest of the three books. While "The Desire Variable" shows explosive, intense scenes between the MCs and "The Passion Parameter" reveals the initial explorations into new territory of their connection, this book is different. The MCs explore their boundaries and limits set against serious dangers and uncertainty. Growing affection and trust occurs both inside and outside the bedroom.

Errors and Consistency: This was a squeaky clean draft. The author uses a clear, consistent voice, and I found no spelling or grammatical errors.

Overall experience: I'M WRECKED. I genuinely don't know what to do with myself. I've waited so long for Book Three, and it was so surprising and satisfying, but now it's over. I laughed, I cried...I cried a lot. I balled up my fists in anger and frustration so many times. I feel such a deep connection with Andy and Lex on such a personal level. There are little bits of them that I see mirrored in myself: Andy's soft but intense heart, Lex's need for distance and control, and their shared need for cerebral attraction to find that deeper connection in another person.
When Book Two ended on such a devastating cliffhanger (Book One's cliffhanger was also cruel), I felt like the air had been sucked from the room. Book Three was like all the oxygen returned to my lungs at once, leaving me delirious, my head spinning.
This is my new favorite trilogy. As a queer person who can really only find deeper affection and attraction through shared intellectual interests, I've never felt so seen by a story; by an author. In my own life, I've found the Lex to my Andy (okay, minus the billionaire part), and I feel so validated by seeing a similar connection between two fictional characters. There were moments that articulated joy, sadness, and attraction in ways I've never been able to articulate myself.
I can't wait to see what Ana D'Arcy pens next. Until then, I'm sure I will reread "Bianary Hearts" another time or two. But for the moment, I need to sit with myself and feel the spectrum of emotions this one left me holding.

[LM · Rating 5 out of 5]

The Love Constant by Ana D’Arcy was a strong and satisfying conclusion to the entire Binary Hearts series. I loved this series from start to finish, and I’m so happy the final book ended just as powerfully as the first one began.

Lex and Andrea feel fated in the best possible way. Their connection is undeniable, and their destiny together feels inevitable. I wish I could say more about the story itself, but I do not want to get into spoilers.

What I especially loved was the slow, thoughtful evolution of both characters, individually and as a couple. Their growth felt natural and meaningful, which made their relationship even more compelling to read. This novel also sent me down a rabbit hole learning more about Asperger’s syndrome and how it can affect relationships, which I found fascinating. Lex processes the world differently, but the book shows that differences in the way someone is wired do not make love impossible. It simply requires patience, understanding, and a willingness from both people to respect each other’s needs and boundaries.

I really appreciated how attentive Lex was to Andy’s cues and needs. At the same time, I loved that Andy was genuinely drawn to Lex’s mannerisms and allowed him to be fully himself, without trying to force him into someone he was not. She appreciated the effort he made to do things that mattered to her, even when those gestures did not necessarily benefit him directly. Her happiness was enough for him, and that was incredibly touching.

Relationships like theirs can be challenging, but Andrea understood who Lex was and never made an attempt to change him. In fact, she loved him more for it. Lex’s brilliant mind was easily his most attractive quality to me. That was what I loved most about him. Of course, the fact that he was insatiable and extremely attractive did not hurt either.

I absolutely loved this novel from beginning to end. I appreciate the bonus chapters and will reread the entire series again very soon, I'm sure. I just want to relive it all. Brilliant writing and unforgettable characters!

[Maria · Rating 5 out of 5]

My honest rating is ♾️/5 ⭐️. This is the third and last book in the Binary Hearts series. I could’ve read it in two afternoons but I delayed the ending of purpose because I didn’t want it to finish, I didn’t want to say goodbye to Andrea and Lex and this story.
In this book there are bits of lots of literary subgenres. There’s love, of course, and smut, but there’s espionage, thriller, mystery, comedy. It’s intense and hooked till the end.
I don’t want to spoil anything but this is the last book in a trilogy and I think read the first two books is almost mandatory. After Lex being arrested, their relationship is suffering from the distance, the lack of communication (not a miscommunication trope, he’s in jail) and how Lex is coping with it. But Andrea is a force of nature and willing to risk everything for the live their deserve. Of course the plot thickens and getting out of all this mess is way more complicated than it seems at the beginning and they have to work in tandem and risk everything to win that happy ever after they deserve.
Ana’s writing is outstanding!!! She deserves all the credit in this world. This book is mind blowing, how she travels from suspense and thriller vibes with comedy, romance and spies!! (There’s even a heist!!!, could you ask for more?)
So if you have the read previous book you need to read this one. If you haven’t read this series: please go!
Tropes you can find in this book:
- workplace romance
- no 3rd act break-up
- dual 1st person POV
- found family
- love against adversity
- smut
- neurodivergent representation
- thriller vibes/ espionage
- woman in STEM

This book has plenty of wide-open door scenes, smut incredible written that will keep you fanning yourself 🥵🥵

I’ve received this book as an ARC and I’d like to thank the author, Ana D’Arcy, for letting me read this book in advance and allow me to give my honest opinion.

[Sophie Knight · Rating 5 out of 5]

Ana D’Arcy has done it again.

I must admit, this is not my first read of this book. Following along from her first original publication, I, and I’m sure many others, have been readily anticipating the release of Andy and Lex’s closing chapter. D’Arcy has an unteachable ability to combine humour and steam with independence and loyalty, allowing each theme to develop without overshadowing another.

The portrayal of each character in this book is meticulously designed to encompass you in their emotions and thought processes as their storylines develop. I truly feel that each person who chooses to pick up this series will be left a better person. As a female in a male dominated STEM industry who is continuously fighting to be seen and respected, I connect strongly to this trilogy. I truly believe ‘The Love Constant’ creates a space for readers of any demographic and background to see a little bit of themselves between the pages.

D’Arcy’s commitment to The Binary Hearts Trilogy is exemplified by how effortless the messages of commitment, trust, vulnerability, and strength are developed - exemplified in ‘The Love Constant’. I truly could not have asked for anything more.

I joined D’Arcy’s kickstarter campaign again not just to show my support of her hard work, but also because I would’ve done anything to read this book sooner!!! If that doesn’t say enough about the impact and excitement she’s created, I don’t know what will 🔥. I’m also not part of the ARC community, so I’m here writing this review purely because I want to recommend and acknowledge the excellence of this book, and hopefully convince someone else to give the trilogy a read!

Thank you, Ana. Thank you for making myself (and I’m sure many others) feel seen.

Okay so listen, Ana was one of the first authors when I started my reading journey again a few years ago (her first book Up the ladder which i’m also obsessed with so go read it pls babies) and since then she is one of my favorite authors because her writing style is so good and the stories she writes are so emotional well written.

So, after having the privilege (because that’s how it feels yes) of reading all three books in this series as an ARC I’m so saddened it’s over, that’s why I added my edits from the previous books 🥹. The story of Andy and Lex is everything and even though I’m utterly devastated that their story is over I’m very happy with the ending, it was so beautiful, even more than I could have expected.

“𝒯𝑜 𝒸𝒶𝓇𝑒 𝒻𝑜𝓇 𝓈𝑜𝓂𝑒𝑜𝓃𝑒 𝓈𝑜 𝓂𝓊𝒸𝒽. 𝒯𝑜 𝓋𝒶𝓁𝓊𝑒 𝓉𝒽𝑒 𝓁𝒾𝒻𝑒 𝑜𝒻 𝒶𝓃𝑜𝓉𝒽𝑒𝓇 𝓅𝑒𝓇𝓈𝑜𝓃 𝓂𝑜𝓇𝑒 𝓉𝒽𝒶𝓃 𝓎𝑜𝓊𝓇 𝑜𝓌𝓃. ℐ𝓉 𝒻𝑒𝑒𝓁𝓈 𝓋𝑒𝓇𝓎 𝓈𝑒𝓁𝒻𝓁𝑒𝓈𝓈, 𝒷𝓊𝓉 𝒶𝓉 𝓉𝒽𝑒 𝓈𝒶𝓂𝑒 𝓉𝒾𝓂𝑒, ℐ’𝓂 𝓈𝑒𝓁𝒻𝒾𝓈𝒽 𝒾𝓃 𝓂𝓎 𝓁𝑜𝓋𝑒 𝒻𝑜𝓇 𝓎𝑜𝓊.”

I never thought I'd be a fan of following a single couple over multiple books, because it surely gets repetitive, right? And you rarely stumble upon a couple that would need more than a single book, right? Well, Ana definitely proved me wrong with this trilogy!

Andy and Lex have been one of the highlights of my year for the last three years, which is insane in the best way. It was such a bittersweet journey reading this, knowing it was the last one. I can never get enough of Ana's writing, of her characters, and of the plots she comes up with. This one kind of dabbled into romantic suspense, broadening the events of the second book and upping the stakes, and I loved it!! It was intense from the start, but we also got a lot of those soft, slow moments between them, balancing it all perfectly. I can't talk about the plot too much without spoiling it, but I absolutely loved it from start to finish. I loved how they overcame everything that stood in their way, going above and beyond for each other, and how that made them even closer.

If you like complex, nerdy, loveable, fierce characters, this might be for you! And if you like big, memorable, diverse, spiiicy romance stories too, then this is definitely for you! Ana truly never disappoints, and I can't wait to see what else she has in store for us!

A huge thank you to the author for sending me an ARC of this book!

♾️ ⭐

How do you say goodbye to a series that has been your comfort for the past 5+ years?

Easy- you don't. Andy&Lex is a ship that I have been sailing since 2020 and now that their last installment is published, they have finally reached their destination. The final book wraps up their tumultuous journey tremendously. Their destination is the most beautiful place you could imagine.

Fair warning though- if you thought the previous books were volatile, think again. This book was everything. It will make you laugh, cry, scream and go mad with rage (all that angst, my goodness 😈). It's powerpacked with emotions that will suck you dry and then bring you back to life (don't worry you will still be crying from downstairs throughout the book 🤪).

It was a perfect lil tornado packed up in a book. Albeit a tornado that sweeps up debris and restores them too after all that destruction, because I like I said- their aftermath is a thing of beauty and not sadness.

The binary hearts series has my whole heart and you will forever find me preaching everyone to go read it.

Ana- thank you for trusting me with your words and letting me beta read this entire series. Thank you for immortalising me in a series I love so dearly, it will never cease to amaze me that I get to be a part of this universe forever. I love you forever and ever!

Lex and Andrea 🥹 They are finally here! And we have their hea 🥵 What a journey, and what a love story! I cried, giggled, kicked my feet, and fell for them so much more 🥹 Thank you so much, Ana Darcy, for this ARC ❤️ Your writing is incredible and beautiful 🥹

Andrea Walker 🔥 She is feistier, braver, sassier and more in love 💃 Andrea is a power Latina and she owns it 🤭 Her character grows even more, and it is incredible to see. Her strength is tested many times, and she emerges victorious 😈 She fights for their love, especially when life is working against them 😖 I adored seeing her banter with Lex, flirt with him, explore more of their kinks and finally find their hea 🥹❤️

Alexander Coleman 😈 If you thought Lex was obsessed and kinky before 💃 You are going to be blushing af! He's still the quiet, intelligent, billionaire who fell head over heels that we know. He will do anything for her smile and to keep her safe. His character has a lot to work through and fight for, to finally have his hea and he does it bravely 🥹 I absolutely adored seeing him come out his shell more, banter with her and show us more of his spicy side 😈

They took risks and argued, but most of all they choose their love 🥹 If there is a couple that owns me, its them 🥵💃 And the spice! Hawt dayum, Ana! You had me constantly reminding myself to keep both hands on the screen 😈

Make sure you read the content warning before starting this book as there are some potentially triggering topics covered. This is the final installment of this trilogy. It picks up right where book 2 left off, and you absolutely cannot read this book without reading the first two. Andrea is a brilliant badass and much less dramatic in this book than she was in the last one. She gets shit done and saves the day left, right, and center in this one. I love that for them, but I love that for her more! I also love that I was wrong about the motives and actions that I thought were alluded to in the last book by a side character, that was an excellent twist. This book was much more suspenseful than the previous two books in the series, so there were lots of twists and turns. I do feel like there were too many twists and turns though. This final book was very long, and it felt a bit like a telenovela. Thankfully this is the last book, so no cliffhangers, and the HEA is complete. As with all of the books in this series, there's a ton of spice, and like I've said before, I could do without so many scenes, but it is satisfying after what they've gone through to see them together and happy.
3.5 stars!

What an epic ending to a phenomenal series. It’s hard to describe this book in its entirety other than the word chaos! Truly and utterly chaotic. Rest assure unlike book 1 and 2 Lex and Andy get their HEA after but my god do they have to work for it. Ana keeps you on this epic roller coaster, the moment you are able to take a breath she throws you through another loop and fully flips it upside down. This book is on the longer end but it felt necessary to give this couple the ending they needed. Lex and Andy hold such a special place in my heart and it was so bitter sweet finishing this book knowing it was the end. But my god am I so happy to have read this book and this whole series. It’s funny and cheesy, it will have you tearing up from beautiful moments and panting from all the slex. This book gets spicy in even more eccentric ways and if you’ve read this couple you know how adventurous they already are. Ana really outdid herself with this one and ended this series on a high. I’m jealous of people who get to read this series for the first time because they are really in for a spectacle time.
5/5 stars spice 3/5

my first five star this year (no surprise there!!) I have followed Andrea and Alexander’s journey since day one. I remember reading the first book and being so excited for Andy and Lex’s happily ever after.

After Lex’s arrest, Andy never gave up and proved over and over again how much of a bad bitch she is. She also never failed to show Lex that there was nothing in this universe that would push her away and make her love Lex less. The thing I have always loved about Lex is that he loved Andy unconditionally. He looked at her with awe and believed in her full potential even if she didn’t believe in herself. I loved seeing these two work together, spend genuine time together and see them being their complete dorky and nerdy selves ❤️

My heart is so full knowing that Lex is part of family that loves him and that him and Andrea were able to have the lives they truly, truly deserved.

I will forever love this series, these characters and all the thanks to Ana D’Arcy for creating this world 💜

I had the absolute pleasure to receive an ARC from the author of the book and I am leaving an honest review.

The Love Constant is book 3 of the Binary Hearts Trilogy.

Your Honor, I love them. This is the best ending for this incredible couple!!! They went through so much in this book. After that cliffhanger, I loved how each one fought for their relationship and safety. They face a lot of challenges and dangers in this part of the trilogy, but come out on top by working as a team and trusting each other. Andy consolidated herself as a badass intelligent heroine. And Lex…learns to trust her intelligence and instincts and to cede control to her. I loved the openness and vulnerability he displayed. They absolutely grow a lot and work for their future. And the chemistry…as always: incendiary!!

I can’t believe this story is over, I was eagerly waiting for this book. And had so much fun reading, it was a rollercoaster of emotions. One moment I could be laughing out loud and the next crying. The bonus chapter was just chef’s kiss, bringing us into the future with them.

I can’t wait to read what Ana writes next!!! Thank you for letting me be on this ARC Team.

I can’t believe this trilogy is over! 😭 I’ve been hooked since book one, and after surviving those two cliffhangers, this finale was absolutely worth the wait🥹🫠

The Love Consonant picks up nine days after book two, continuing Andrea and Lex’s story. Without giving anything away, Andrea Walker proves once again that she’s a total force: brilliant, bold, and maybe a tiny bit insane. I loved how fiercely she cared for Lex and how determined she was to shape her own future with Lex.

This book was filled with suspense, chaos, and love, which made it fly by. The amount of detail and care that went into building this world really shows. It’s a long read for a trilogy, but it never drags, and I was completely invested in Andrea and Lex’s journey from start to finish. I’m sad there won’t be another book but the ending was such an amazing way to end all the chaos and watch them finally have a happy peaceful ending😭❤️

If you love STEM romance with tension, spice, and two very passionate nerdy characters, you’ll want to pick up this series.

Thank you to @authoranadarcy for the eARC and the wild adventure❤️

ARC REVIEW 💜

Ana D’Arcy is back with another BANGER!!

Listennnn,
I loved the first 2 books in the series! Truly! They’re both 2 of my favorite books ever !

But this one 🤭

This book right here, is just on another level 🤯

I could’ve easily read it in 1 sitting, but I didn’t because I wanted to savor it. I was SO EXCITED to be back with the nerds and finally get to know what happened after the crazy cliffhanger in book 2 but I also wasn’t ready to say goodbye to them yet 🥺

To say Ana pulled at my heartstrings with this one is an understatement. Andrea & Lex went through so much in this book! But I also lovedddd how these events brought out the badass b*tch inside Andrea 🤭 I was 100% here for it & she did not disappoint! Oh no she did not!

I feel like i highlighted half of the book lol 😂

YES IT WAS THAT GOOD

This book also has the BEST epilogue I’ve ever read ! 11/10 ! It was so incredibly well done & well written. It ended the series PERFECTLY 🩷

Oh & obviously the spice was god tier 😌

I am so incredibly sad that the series is over but I truly cannot wait for more Ana D’arcy books in the future.

⭐️⭐️⭐️⭐️⭐️
