Another masterful book in the series. I promptly dropped everything when this ARC came to me, because obvs I was gonna do that, and it was worth it. I loved how no nonsense Charlie was and how protective she was of Novak. Also loved that she was over 40 and had was wicked smart. Novak was just the sweetest in his own intense way and needed someone like Charlie to show him his existence wasn’t justification for his treatment. He was up to his ears in his trauma and it made him very resistant to the idea of a relationship and Charlie was a respectful bulldozer to those insecurities the best way she knew how.

This continues to be one of the best sci fi romance series, story-wise. I am as invested in the future of Renata as I am its inhabitants.
The romance in this one is very sex focused with very few moments of actual intimacy and friendship. I love both of these characters and wanted to see them grow together more.
On a nitpicky note, this had an eye-twitching number of mistakes overlooked in proofreading. I don't remember this being an issue in Etta Pierce's other titles. Mostly homophones that will slip past a spellchecker, and a few straight-up typos.

ARC // Another enjoyable installment in the series. It’s clear that we are setting up the final pieces toward the inevitable conclusion.
We get an appearance from Ezraji and Amelia (MCs of book 3) and their continued happiness that intentionally contrasts with the unceasing threat to the human colony expertly told through Ferulis’s pivotal POV. His joys and frustrations were palpable—truthfully my favorite part of the book.
Novak’s story was exactly as I expected: fearsome, deadly, and clever with a tragic existence. Charlie was equally fierce, brilliant and brave. Their qualities were quite complimentary. I loved the beginning of their story as their initial encounter is so different than in the previous books. I definitely was nodding along with Charlie’s reaction to Novak because same, he’s my favorite too. But as the story progressed so little time was spent together and frequently in the company of others so any tension that blossomed in their beginning waned. There wasn’t much relationship development and I never felt an emotional connection between them. Lust bordering on feral? Absolutely. Possessiveness, too, but the intimacy I expect from a Romance wasn’t there.
Still it is very much a fantastic story that adds to the mystery of the ultimate end and I highly recommend it.

This has to be one of my favorite series.
This one wasn't my favorite. The MMC just read as weak. I'm not really sure how he could actually do his job when he's constantly overcome and distracted. Still a decent read, tho.

I was conflicted over my rating for DEFIANCE because I did like it but it just didn't feel as good as previous books in the series and it had an overall rushed feeling without doing much to advance the overall plot.
On the positive side, I loved Charlie and Novak as individual characters. Novak has popped up here and there throughout the series but now we finally got to learn more about him and a bit more about advenans. I enjoyed watching him soften for Charlie and realize that he was allowed to find happiness in his life. And Charlie was also a delight, a bit rough around the edges but with a heart of gold. She was compassionate and brave and I loved her inquisitive and curious personality. I did like them as a couple but their romance is where things started to stumble a bit for me.
I want to be clear this book is NOT a love triangle, but there was way too much time spent on Sath. I liked his character but it felt like Charlie spent more time with him than she did with Novak and since he was personally interested in her, albeit in a fairly non-sexual way, it muddied the romance that was supposed to be happening between Charlie and Novak. Charlie spent a ton of time with Sath, she learned all about the hjarna people and his family and his culture when she should have been learning those things about Novak. He hardly tells her anything about his past or the way his people are regulated and controlled by the ISU. There was a definite lack of intimacy between Novak and Charlie; it was obvious they were physically attracted to each other and were starting to care for each other, but I never felt like they spent enough time together to actually fall in love.
While this book felt a bit flat for me and was my least favorite of the series, despite how much I loved the MCs, I'm still looking forward to more in the series because Pierce has created a truly interesting and unique alien world.

Defiance is the next book in the Intersolar Union series. This action packed sci-fi novel features Charlie, an Irish ichthyologist, and Novak, an advenan covert elite, and their plan to catch the Union’s latest villain, a hjarna who is known to be creating robot dolls from the rescued human’s DNA and likeness.
Pierce has got such an engaging storyline going in this sci-fi series. The mystery and plot twists have kept me hooked from the beginning. This book, much like the others, is fast paced and bursting with intrigue.
Pierce’s female characters are a consistent high point for me in her books. Charlie fits right in with these other strong, smart women. I love her resilience, authenticity, and overall good nature. She has been handed the raw end of the deal over and over in life yet continues to move forward, caring for others and trying to make the most of her new life. She is a great fit for Novak, someone who has also been given the short end of the stick over the course of this life. Together this pair finds acceptance and loyalty - they were so easy to root for!
Maybe I am just a sap, but I would have loved to have read one or two more scenes with Novak and Charlie sharing experiences that helped build an authentic friendship between them. Novak’s species naturally has strong primal urges towards their mates. That seemed to be the dominant factor in his connection to Charlie. Since humans do not have the same biological drives or scent attraction, I think their relationship would’ve been even richer if it was balanced with a few more non-sexual or scent driven activities.
Also - a big yeehaw for a side character that didn’t turn out to be duplicitous. I’m looking at you, yellow sparkly dude. Thank you for your service to the Union.
Overall, this book was great (I’d expect nothing less from Pierce at this point). Be sure to read the books prior, then hop in and enjoy!

I would have loved more tension and build up between Novak and Charlie! I did enjoy Novak but I would have loved to see more possessiveness and more time spent between the main characters. I needed more interaction!

A galaxy spanning James Bond-esque backstory with sizzling romance!
Wow, an amazing and riveting story. An interesting developing romance between Charlie (human woman; Charlotte) and Novak (male advenan (think Anubis-like)). It has echoes, in the best way, of James Bond in the tantalizing attraction between Charlie and Novak while they play “spies” in an intergalactic plot. This book would be best enjoyed if you’ve read all of the prior books, however, if the intrigue of a tantalizing romantic interest with witty dialogue and some James Bond-esque backstory, then jump right in. Charlie comes to life as a woman in her forties, with gorgeous light red hair, freckles and the brash no nonsense attitude of an Irish woman. She meets and starts working with Novak, a tall Anubis-like “advenan”. His tall stature, desirable physique and protective nature are just the first things to engage her interest. There is much more depth to him than just a “man-in-black” covert type. They have a heady spiciness to their encounters all their own. For those who’ve read the prior books, you won’t be disappointed. The intrigue and increasing complexities of the galactic politics in play are truly astounding. Of course, several threads of intrigue are unveiled, but there are still some questions to be answered. This story keeps you riveted to the end. In my humble opinion, Etta Pierce’s books are a sure thing, they never disappoint. For my fellow geeks out there, Pierce adds so much thought into the creation of her alien species’ biology, this particular book will definitely appeal to all ichthyologically-inclined readers out there.

This sucks because I love the Advenans so much but I felt let down with this pairing. Plot wise it was awesome and it kept me reading from start to finish. 3/5 stars as a romance but 5/5 for sci-fi thriller.
I enjoyed it but it was short and am I crazy or did the MCs not actually spend much time getting to know each other? She was practically "dating" another alien the whole mission and he tagged along as bodyguard.
For me, the 1st sex scene was too early on. Then they didn't develop enough of an emotional bond for me to really be convinced of their HEA, especially as he'll continue to be a Guild leader and go off planet often.
I dunno. Just not my favorite of the series. I'd call it spicy sci-fi thriller more than romance.

*4.5 stars* This series is just so exciting. The overarching plot of the book (and series) is high stakes and action packed, and always delivers. It took me a second to figure out where in the timeline this book takes place, but once that felt clear it did add closure to a certain plot point so that we can move forward in the series and also gain a lot more world building. Very smart. This series is best read in order, although there are three standalones that can be read any time.
It was such a treat to be back in this world. I also have to say I LOVED Novak. He’s terrifying and dangerous, a misunderstood, lonesome alien and he’s also just baby girl. Novak and Charlie are wonderful together. I also really loved that we get a truly *good* side character/new friend. My only small complaint is that I wanted even more of them together, building their romance, particularly at the beginning. But for a quick interlude in this bigger series, it worked well.

I was so excited to read Novak and Charlie's story. But there was very little emotional intimacy and romance. By the end, I felt like I knew almost nothing about either character, so what could they possibly know about each other?
Also, while I love this series and this universe, there's a severe lack of explanation in the books. Some of it might be because it was explained in a previous book, but a lot of it is cultural and world building details that are just never given the time on the page. Which seriously takes me out of the book. I feel like I'm lost or playing catch-up instead of getting immersed.
The same thing happens with scenes that are busy whether that's action or some event. There's just not enough details to pull me into it.

Holy shit. Etta Pierce has me in her GRIP with this series! Read it in a week which considering the length of these novels is impressive, even for me, but that's saying something!

Charlie Galloway (43 year old Irish red head, scientist) and Novak Gaul (cover elite Advenan - think Jackal/Dragon Alien) were two of my favourite characters so far in the series. This book was action packed, Novak was affection starved and Charlie would have none of it. She left him know exactly what she wanted. The plot of the series was the main focus and am I left wanting more about Charlie and Novak's relationship but this was an amazing installment in the series. Excited for the next book, as always!

This book was INSANELY GOOD. Charlie was a perfect FMC. In her 40s, relatable as hell. NOVAK. Novakkkkkkk. Thirst trap Novak. Ioofffff 🔥🥵🔥🥵🔥also the plot is PLOTTING. Chef’s kiss.

Plot
The story follows Charlie and Novak as they travel to another planet to sniff out, literally, the source of the human doll industry.
The pacing on this story was a bit more off than those previously - it's not a long book and a great chunk of the beginning is taken up with snippets of other MC's, so the two don't actually meet for quite a while. Then Charlie spends way too much time with a side character and Novak kinda get stuffed in the closet, with a pretty rushed ending. The knock on effect for me was that the world building didn't quite keep up either, with important information, like Novak's unique *ahem* anatomy, being kinda glossed over a bit. I need DETAIL Etta, DETAIL.
Characters
FMC
I'm not sure how I feel about Charlie- she's a spunky individual, but she's also a big convenient plot device for the story given her background with fish, which I found more annoying that I thought I would. Other than that she felt pretty flat to me. I do however always love a STEM MC, and I did enjoy learning about some of the fishy topics more than I thought I would.
MMC
I actually really liked Novak - he did his job and did it well, and was just a general nice guy. We got a glimpse into his personal background, but I didn't feel that his overall species backstory was properly explained. Other than being 'a bit dangerous', why do they make their weird deposits? Why are they under such strict control while the other species aren't? There were some vague explanations, but it left me a bit unsatisfied on the whole. Even his downstairs business, whilst incredibly intriguing, was difficult to picture and that is a crime in this book genre.
The Rest
There are other characters, but they blended a little into one. The main tour guide, whose name I have completely forgotten *checks notes* Sath, was mostly just annoying and I found his advances towards Charlie pretty awkward. I still didn't understand how they mated at all, something asexual? Spawning? Or was the spawning something else?
The Chemistry
This is a classic story of physical attraction insta-love. I don't really know why Novak would actually like Charlie, other than her smelling nice. They spend so little actual time together without their camel-cock-blocker that it's a miracle they got to know each other at all.
The Good
Finally getting Novak's story! And he's got a funky peen.
The Bad
The missing world building and species explanations.
The Ugly
No uglies.
The Wrap Up
Who let the Avenan's out? Who? Who?

***Arc Review***
3.75 rounded up to 4 stars
Defiance is a solid continuation of the Intersolar Union series. The first half of the book does a great job of giving us updates and details on the world, and where we are with the overarching plot. MCs from previous books make appearances here, but in a way that moves the plot forward and makes sense, not just for a quick cameo. It took me a while to remember all the mate pairings and world politics, and I really appreciated the guide at the front of the book!
The first half is also when we get to know our heroine, Charlie. One of the things I love about Pierce's books is that she writes women of varied backgrounds, ages, and ethnicity. Charlie is a 43 year old ichthyologist (fish scientist) dealing with perimenopause (relatable). Her job is relevant throughout the book - she has a greater understanding of adaptive traits and how they're expressed in different species, so we seeing each alien through her eyes is super interesting. She doesn't see them as scary or weird; she approaches with curiosity and wants to understand why they are the way they are.
While I really liked the book overall, I didn't quite feel the connection between the two MCs in this book. Novak is absolutely feral for her, but beyond that, there just wasn't as much emotional intimacy, and it made it harder for me to buy into their relationship. Still, the world that Pierce has built is really interesting and well done!
The good:
-Older FMC with a unique profession
-MMC with really interesting biological drives as a predator/hunter
-His tail is basically a third MC in this one- it's possessive and always wanting to touch her, and Novak has to literally hold on to it to keep it under control. I was cracking up reading about its antics
-Sexual tension between the two was top notch. Novak is biologically suited to tracking and hunting, and Charlie understands how to work with his instincts to make tracking her easier and more enjoyable for him.
-Characters that we might think are "bad" are given more depth so we understand the reason behind their actions. We've seen Commander Xata pop up in previous books, and while she's an ally, she's also come across as cold and mean. In this book, we learn why she is so bitter towards humans, and understand the plight of her species.
-It was brief, but I liked the commentary on cultural appropriation, coming from the perspective of human vs. alien.
-Charlie standing up for Novak, to others and to himself, and demanding that they see him as a whole being
The not so good:
-I didn't feel like we saw them connect or grow the relationship. Even halfway through the book, they hadn't really gotten to know each other at all
-When they do finally make the connection, it happens off-page, 3/4 of the way through the book. It's told to us after the fact, so we don't get to experience it with them. It makes it feel disconnected, so we just have to sort of trust that they built that intimacy and understanding of each other.
-The pacing was a little funky. A lot had to be squeezed into the last 10% of the book, so the comeuppance we've been waiting for happens off-page. That was a bit of a let down after so many books building towards this. I would've been happy to read a longer book that gives the resolution the time it needs.
-Charlie slaps Novak in the face. That's a hard no for me. Not only did it feel out of place and unnecessary, but I have zero interest in reading about partners who do that to each other.
Still, I did enjoy the book, and I'm super curious to see where the series goes from here!

Charlie is a 43 year old ichthyologist (fish scientist) dealing with perimenopause (relatable). Her job is relevant throughout the book - she has a greater understanding of adaptive traits and how they're expressed in different species, so we seeing each alien through her eyes is super interesting. She doesn't see them as scary or weird; she approaches with curiosity and wants to understand why they are the way they are.
While I really liked the book overall, I didn't quite feel the connection between the two MCs in this book. Novak is absolutely feral for her, but beyond that, there just wasn't as much emotional intimacy, and it made it harder for me to buy into their relationship. Still, the world that Pierce has built is really interesting and well done!
The good:
-Older FMC with a unique profession
-MMC with really interesting biological drives as a predator/hunter
-His tail is basically a third MC in this one- it's possessive and always wanting to touch her, and Novak has to literally hold on to it to keep it under control. I was cracking up reading about its antics
-Sexual tension between the two was top notch. Novak is biologically suited to tracking and hunting, and Charlie understands how to work with his instincts to make tracking her easier and more enjoyable for him.
-Characters that we might think are "bad" are given more depth so we understand the reason behind their actions. We've seen Commander Xata pop up in previous books, and while she's an ally, she's also come across as cold and mean. In this book, we learn why she is so bitter towards humans, and understand the plight of her species.
-It was brief, but I liked the commentary on cultural appropriation, coming from the perspective of human vs. alien.
-Charlie standing up for Novak, to others and to himself, and demanding that they see him as a whole being
The not so good:
-I didn't feel like we saw them connect or grow the relationship. Even halfway through the book, they hadn't really gotten to know each other at all
-When they do finally make the connection, it happens off-page, 3/4 of the way through the book. It's told to us after the fact, so we don't get to experience it with them. It makes it feel disconnected, so we just have to sort of trust that they built that intimacy and understanding of each other.
-The pacing was a little funky. A lot had to be squeezed into the last 10% of the book, so the comeuppance we've been waiting for happens off-page. That was a bit of a let down after so many books building towards this. I would've been happy to read a longer book that gives the resolution the time it needs.
-Charlie slaps Novak in the face. That's a hard no for me. Not only did it feel out of place and unnecessary, but I have zero interest in reading about partners who do that to each other.
Still, I did enjoy the book, and I'm super curious to see where the series goes from here!

Series: Intersolar Union #7
Rating: 4 stars - It was really good
Novak Gaul is a free agent on a short leash. Usually he can forget that his life isn’t his own, but when he captures a woman's scent that calls to him like she was meant to be his, he runs the other way so he doesn’t risk the consequences. But when his boss calls in a favor, he finds himself working with that woman to help capture the enemy, even if it means letting her get captured to do it.
After meeting Novak in the previous books I was very curious to get his story and see him fall in love. Novak is a covert elite but because he is also an advenan he is on a short leash. His species is used for diversity breeding and has aphrodisiac venom so the government heavily controls his species and treats them like second class citizens. It was heartbreaking to learn everything that Novak has been through to get where he is today. He was a strong and protective male who was hiding a heart of gold.
Charlie is a 43 year old Irish ichthyologist (study of fish) who jumps at a chance to explore more of the universe and their aquatic species. She knows she is playing the role of bait but she uses this as an opportunity to learn and make contacts outside of Renata. I loved how straightforward she was. She wasn’t afraid to flat out tell Novak she wanted him or speak out against the mistreatment of his species. She was a fantastic heroine and I really loved her.
Novak and Charlie have a forbidden relationship because advenans are considered lower class and ruled by their instincts. Charlie can tell that the whole race is being punished for the act of a few individuals though and follows her heart. I really loved how sweet and protective Novak ended up being with Charlie. We really see him open up and show all his scars, and I loved it. The whole idea of a chemia (scent basically) being used to track across planets was fascinating. Basically, I really loved these two and really hope we get to see more of them in future books.
This one also finally saw some resolution with the attempted kidnapping of humans for their living code. Charlie is playing bait to try and capture Councilwoman Guei, who we meet in the previous book and found was buying living code to make clones. I enjoyed the whole storyline of trying to trap and capture Guei. It was an interesting trap, even if it did lead to Charlie being captured, but it lead to the outcome they were wanting. I also liked that while this was the main point of Charlie leaving Renata, it was overshadowing the relationship growing between Novak and Charlie, it just helped it grow stronger.
Overall, this was another fantastic book for this series. I really can’t wait to see what will happen next for Renata and the humans who inhabit it.

This is a really good series all in all. This particular book felt rushed. I will say that I was confused for a good chunk of the beginning as to why the mmc was in a “bullpen” and why so much of his species was shameful. I figured out that it was sexual in nature somehow, and we get a bit of further explanation towards the end of the book, but it would have been nice to get that earlier.
I had…. Forgotten that the mmc ‘met’ the fmc before? Must have happened during a quick scene with other stuff going on because I sure don’t remember it happening.
As others have remarked, a majority of the scenes between the mc’s was with spice… which… left things feeling superficial. Another thing I will say is: the technical aspects of the mc’s body dragged my attention away from the sexy vibes, because I kept getting caught up on how his body had so much going on at once. Head of a jackal, olfactory scenes of a snake, a lizard tail that was almost its own sentience… scales that were actually feather proteins that acted like Venetian blinds and could cut people… fangs that could be moved, along with poison sacs at their base that were used during sex to erotically subdue… three curly cue peni that could spiral into one… cloaca…
I mean, I don’t mind alien aliens. I really don’t. And it’s obvious the author enjoys the technical aspects. But it was just a lot to keep track of. And their first sex scene was outside in a swamp. I lived in the South and let me tell you… that shit ain’t sexy.
I did like the fmc being in her 40’s. I liked that she felt times of self doubt as well as times when she dgaf, which is one of the perks of being in your 40’s.
Jharim, the bionic, acted a bit squirrelly towards Charlie (fmc) with a short kinda flirty scene. I guess he’s bi or pan maybe? Not sure where the author is going with the flirting but it was kind of confusing. I guess we’ll have to wait and see if there will be a mmf book with him and his bionic twink with another Renatian human female. :P
I was glad that Sparkles was not a traitor. Would be nice for him to have his human hybrid spawn dreams come true in a future book.
This book was short compared to the other books. I’m kind of nervous about the next books to see how everything turns out. Can’t wait for Ferulis’ book. He deserves someone to massage his old bone. 🤭🥹

5 stars doesn't feel like enough...
I’ve said it before and I’ll keep saying it ‘til I’m blue in the face—Etta Pierce’s approach to diversity is unmatched. No one feels like a token. No one’s just a box to tick off. If one of her FMCs is a particular ethnicity, it goes so far beyond skin tone or hair texture—they’re soaked in their culture. From the food they eat to the slang they use (yes, I read Chapter 1 in an Irish accent 🫣), every character lives and breathes like a real person.
Even the alien MMCs have detailed biology and traditions—Etta’s worldbuilding is so rich, her Patreon should come with a warning label: “May cause obsession.” I will never, ever get over how beautifully her main characters are written.
I loved that Charlie is her own woman, she will happily deck you in defense of herself or someone she loves. She's fierce but so loving and sweet. She's known pain but it's made her gentle with a take no shit attitude, rather than cold.
Novak hasn't had an easy life either the heavy policing of his species meant he has never known true freedom, always being used for other people's convenience and pleasure... until he met Charlie and she looked at him like he was worth something. Like he actually matters.
Defiance is a brilliant spy mission of a novel disguised as a humanitarian/charity event with Charlie being the bait for the one behind the Human Dolls with Living Code after a last minute swap with Imani. I was gripped from start to finish but those last 50 or so pages had me white-knuckling my Kindle and trying to figure out how to read faster! The epilogue was so beautifully satisfying that I was smiling from ear to ear.
I can't wait for the next book but also slightly terrified for it as in Etta's own words "not everyone will survive" 😱😱😱
🌙 Would recommend if you love:
🖤 Rich cultural worldbuilding
🖤 Aliens that feel truly alien (in the best, lore-deep way)
🖤 Complex characters who feel like real people, not archetypes
🖤 Emotional payoff that hits just right

While this story has it's roots in "the big miscommunication" trope - which I normally find extremely irritating, the characters handled their differences in culture that lead up to the miscommunication of intent with maturity and kept changing and growing over the course of the extremely fast-paced book. Without having any kind of big blow-up or uncomfortable chat, and just observing one another and the world around them, each character came to understand where traditions, rights, cultural pressure, and injustice had lead them to misunderstand the other's desires in a way that felt weirdly natural for a book that included multiple alien cultures and species.
The read was extremely quick, once I reviewed the character and species lists well enough to refresh my memory of who had tentacles and who had fangs. Per usual, I enjoyed the extremely diverse number of alien physiologies described and how their cultures developed based on those traits and characteristics. I also enjoyed the consistency of the different personalities and how they could be moved to work together or against each other despite grating on one another's nerves or finding one another fun or attractive or alien or repulsive. The "mature" personalities rang true in their impatience with cultural norms in a way that was distinct and different from the impatience of youthful characters for the same.
The only reason I took off a star was that the ending felt somewhat rushed and incomplete. I imagine it was left so because of how the end of this book will tie into a future book and characters, and I can forgive the faint pang of dis-satisfaction over the lack of "event processing" I would expect to see from these characters, if it means that Ms. Pierce hasn't left me waiting for the next book on the edge of a cliff hanger. That's just mean and I don't need it to ensure that I'll be back with grabby hands whenever the next book becomes available.

Defiance brings a whole new planetary experience to the ISU! The ongoing world building continues to be absolutely SCRUMPTIOUS.
Charlie: early 40s, Irish, full of spunk with cheeky quips galore, history of a messy divorce and voluntary hysterectomy, background in STEM but is also a multi tool as far as skills go and an honest desire to be a valuable contributor as a member of the Human colony / human kind.
Novak: age unknown but clearly mature and has lived an eventful tough life, alien resembling the Egyptian jackal god Anubis but mixed with a dragon, history of being used and his species being seen as only useful as a tool but being seen as inherently dangerous and untrustworthy by the broader galactic community, equivalent of a military special ops operator / special agent + guild leader.
The plot thickens with the dolls created from stolen DNA from female colonists like Charlie and Imani and their creators making big moves, interplanetary intrigue bubbles when Charlie visits the Hjarna home world as a Human ambassador and learns more about how the other species views one another, and the knowledge that the Advenans unique (and prohibited) ability to find their 'marked prey' in what's known as The Hunt....
Defiance hits the ground running and the heat turns on early on and continues to simmer throughout.
I love the intricacies and attention to detail Etta puts into all of her character back stories and how the further we go into the series, more and more of what she's introduced previously becomes evidently crafted and shown precisely and deliberately.
As with every ISU novel, I ate this up. Ettas prose is so flavourful and Defiance lingers on the tongue - thick, sweet and savoury and begging for another taste. I'm excited for the next installment and am looking forward to rereading the entire series again and again

I'm always so excited for another book from Etta Pierce. Defiance continues with the storyline of the overarching plot within her Intersolar Union series. However, what's a main plot without some romance thrown in?! Etta always delivers excellent world building, characters, and romance with a pinch of spice. Okay a little bit more than a pinch but its not overwhelming and I love that.
I throughly enjoy reading Etta Pierce's books because each character is so more complex than you initially think.
We've seen Novak Gual throughout other books in the series. He always gave off such confidence and mystery and I was extremely curious about his story. I did not expect some of his background and it fleshed out the character so much. Provided additional insight and showed some vulnerability.
As for Charlie, it was so nice to see a older FMC!! A woman in her 40s and divorced! As I've gotten older I find it at times hard to relate to the FMCs in their early 20s. I really loved Charlie's mentality, and the fact that she was agreeable right off the bat to work Novak. Of course there were fears and anxiety, but she pushed through and got to work. Exactly how I love my FMCs, life deals you crap and you learn to deal with it and move on.
I've said it before and I'll say it again, I absolutely love the mentality of all the FMCs in Etta's work. The FMCs are tough, competent, and smart. I can really feel a connection with the women. They will analyze the situation they are given and then are determined to work through it.
Those that are familiar with these books, heads up, I sympathize with Commander Siat! 😱😱 I never thought I would after knowing what she did with Vin. Shes not 100% redeemed and I don't like her, but after her explanation, I understand her.

> Scent Burn
We’re back in the ISU with a new book, and Defiance doesn’t pull any punches. In order to take down a powerful politician, an advenan Covert Elite Novak Gaul must use Charlie Halloway as bait -the tempting, forbidden human he’s been obsessing over.
Neither Novak nor Charlie are your typical MCs, and getting to see him claim his mate and a home feels like a ‘at last’ kind of moment. It was so easy to not only get swept up in these characters and plot but also the impressive expanding world building and the attention to detail in the alien species and cultures.
I’m truly impressed with how the author is able to introduce a new alien species along with their own culture to the reader, let us get an insight in how they see themselves, their species, and how other aliens view them. So much care and attention that I absolutely love to see.
There is so much depth and heart in these books, not to mention so much for me to theorize over. The Intersolar Union series remain a favorite series that I can pick up at anytime and remind myself why I love this series and characters so much.
Other notables✨
•We finally get to welcome the first human/alien offspring on the colony
•A closer look at Advenans and Hjarnas
•Ferulis!!! I love the cranky Chairman, and am eagerly awaiting his book lol. I loved getting ti see him in this book.
•A spotlight on the secondary characters. I love all the characters in this series but it was really fun getting more of characters we don’t see as often. This also made me really want a hjarna to get a book 🤞

Novak knows Charlie before he meets her. He knows her scent, the set of her shoulders, the color of her hair but he doesn't really know her. When the opportunity comes for him to choose a partner for a mission he chooses Charlie based on her scent and the way that her smell makes him feel. Charlie is one of the human women who has survived her abduction and is trying to find her way; carving out a life for herself the best way that she can given the tools that she has. When Novak and Charlie finally meet, there's heat, there's attraction and there's a huge misunderstanding born of past mistakes and perceptions. The two soldier on and what we get is the story of two deeply bruised and damaged souls finding their way to healing. I was skeptical, he looks like Anubis and she's human but the two make it work despite the odds. Despite the danger because this isn't just a story about Charlie and Novak this is the next piece in the Intersolar Union series. Story is told from dual POV and though part of a series can be read on it's own. Having read some of the other books I do like integration of past characters and the addressing of issues that some of the species may face moving forward. Admittedly I am somewhat curious about what Charlie had been on the cusp of finding in the water but that seems like something for another day.

Defiance, no. 7 in the series, intros a new alien species and the mystery of who is plotting against Renata continues to twist and turn.
Novak Gaul is an Advenan, a super-fertile and supposedly aggressive species, that to humans bare a striking resemblance to the Egyptian god Anubis. Charlie Holloway is a forty year old biologist, still trying to find her place in colony life. When the opportunity arises to take out a key enemy of Renata, the two are thrown together as bodyguard-diplomat in a trap for their enemies with Charlie as bait.
If you’re for more of Pierce’s signature super-rich character and world building, you will not be disappointed. Pierce has given us glimpses of the Advenans before but here we get a more detailed look into their lives as highly regulated outcasts, looked at with suspicion by the Shilpakaar, Hjarna and others while being eroticized and exploited for their unique biological abilities that make Diversification possible.
Charlie and Novak have an interesting dynamic as diplomat and bodyguard, with great chemistry, Charlie the sunny extrovert and Novak the quiet muscle. This one starts fast but still rewards with a slow burn on the back end. I could have used a little more post-action wrap up but in the end this is another satisfying installment in the series.

This one starts fast but still rewards with a slow burn on the back end. I could have used a little more post-action wrap up but in the end this is another satisfying installment in the series.

I have really loved Pierce's work and especially her alien universe because of the details and worldbuilding, and the development of the relationship(s). I loved Novak and Charlie and really liked that this one progressed the overarching story of the series, while introducing new characters/showing us some of our faves, but I do believe that there could have been a bit more development in Novak and Charlie's relationship.
There's a third character (not a love triangle) who is introduced but spends a lot of time with Charlie, and I think part of it is that because the book is shorter than some of the others in the series, it feels like less time was spent with Novak and Charlie when that's maybe not completely true? It's hard to know if the other character is meant to be sequel bait since there's so many folks already in the universe, or just another way to get a POV into the larger universe that Renata a part of.
I also really liked getting more development on how alien men are treated/trying to deal with their world because of the various societal issues, and that it was slightly less high stakes than usual, since the next ones are probably going to be wild roller-coasters.
I'm excited to see what Pierce does next in the universe but also hope we get to see more of Novak and Charlie in the remaining books.

This story is mostly dual POV, with male lead and other perspectives in third person and female lead in first person, well written, and is a forbidden bodyguard/protectee romance in a darker sci fi setting containing a female human ichthyologist (Charlie/Charlotte) and a male advenan (think Anubis appearance) alien warrior/survivor (Novak). I deeply appreciated the vulnerabilities of both characters clearly demonstrated. I adored seeing Novak realise that he wanted more than had been offered and exactly what was forbidden for his species. I enjoyed Charlie’s pragmatic approach to the task she was asked to execute. I adored the upfront acceptance of her physical situation and that it facilitated Charlie and Novak’s relationship. I enjoyed the intimate scenes and how the deepening intimacy reflected the burgeoning relationship. I enjoyed the complexity and detail of the non-romance plot and how the author is unravelling that through each story. I appreciated the cleverness of the tale and the engaged and engaging secondary characters. The author specifies that this story is best read in sequence for the series and I confirm this is true.
I received a complimentary copy from the author and this is my voluntary honest review.

C.J. Redwine's Defiance, a thrilling YA fantasy, immerses readers in a post-apocalyptic world within the walled city of Baalboden. Rachel, unlike other girls, is trained in tracking and combat, defying societal norms where women are controlled by male Protectors. When her courier father disappears, presumed dead by the tyrannical Commander, Rachel embarks on a dangerous journey into the Wasteland to find him, accompanied by Logan, her former love and newfound Protector.
The book is praised for its strong female lead, Rachel, and the dynamic, passionate relationship that blossoms between her and Logan as they face the brutal realities of the Wasteland, including a fearsome monster and ruthless assassins. Redwine's descriptive writing and unique blend of post-apocalyptic, fantasy, and even steampunk elements create a captivating and original world. While some readers found the pacing uneven at times, with action sequences feeling drawn out, others appreciated the intricate plot, character development, and the emotional depth infused throughout the narrative. Overall, Defiance is recommended for fans of dystopian fantasy and adventurous love stories featuring strong, defiant heroines

My favourite alien romance series. And I loved this book! A bodyguard romance with a forbidden alien bad boy? Yes. Always. This was an especially good one because—quite frankly—Etta Pierce is the best character writer in the game.
Our Irish heroine was so Irish that my thoughts started to have an accent. And she was the fish biologist-iest fish biologist character to ever fish biologist. Truly—her brain was pure ichthyology. I loved exploring the deeper science-y side of this sci-fi universe with her.
And our hero was hot. Very “I will find you anywhere” stalking but for a good, protector-y cause. He was a new-to-us type of alien in this universe. Very weird.
And this alien romance did my favourite thing an alien romance can do: be a social commentary about racism and xenophobia (or ableism or any other dehumanizing -ism). Because the way the broader alien universe both fetishized his sexuality and over-policed his body was massively side-eyeing the way white people Other racialized men.
And this book was a trick. I won’t tell you *why* I think that. But this book is a sneaky sneak and I don’t trust its role this series’ overarching plot one bit.
In a fun way that makes me NEED the next book.
