okay listen, I'm not a dirty person but I literally had to force myself to stop reading so I could go take a shower. this is the perfect blend of spice and suspense. It brought back all the atmospheric feels of Twilight while instantly falling in love with Katherine the FMC who is so relatable. Zayn is literally the definition of tall dark and handsome AND he cooks, in the kitchen and in the bedroom. 😉

Dr. Katherine Pearson is a psychologist who returns to the PNW after her father's death. Zayn is the son of the groundskeeper of Katherine's father's estate and unbeknownst to her, her long time stalker. but not in the creepy way, in the - I love you, I care about you, I promised your father I would look after you - kind of way. Zayn weaves his way into the doc's life and always shows up in the right place as the right time.

I really don't want to say too much as I don't want to spoil anything for you, just go pre-order the book you won't be disappointed.

Thank you K. Hollow for letting me read this as an ARC

After months of getting glimpses into Kat’s story, I was profoundly lucky to be able to immerse myself into her world in a single afternoon and into the evening. Her grief, her quiet longing, and her self-imposed solitude grabbed me from the very beginning.

Perfectly situated in the Pacific Northwest, the atmosphere reads dreary and wet just like the main character. Wet? Yes. Because the connection between her and Zayn leaves little to the imagination and much to anticipate. Boiling sensuality and lust tip over into a love that rides the rest of the story. Zayn matches her darkness in a way that’s sometimes comforting and other times terrifying and yet, that quiet storm can’t be denied as you cheer him on.

The story climaxes with a different Kat — changed in ways she didn’t expect — and leaves you feeling more than satisfied. That is to say, maybe wanting the story to continue with just one more bedroom tryst.

GUYS! THIS BOOK IS SO GOSH DARN GOOD!

I usually take awhile to “warm up” to a book, but I was sucked in by the end of the prologue here.

Hollow has a talent for atmospheric writing without making the prose too heavy or complex. It makes for an easy and immersive read!

And let’s talk about that MMC! Omg! The way this man had me blushing, swooning, giggling, and laughing. His POV’s are an absolute treat, and balance so well with the FMC’s.

This book reminded me of Lights Out in its balance between cozy/fun and suspense/dark. Sometimes my heart was racing, sometimes I was kicking my feeties, sometimes I was cuddling my cat and feeling the warm fuzzies.

Definitely worth a read! Very excited for the next book in the series!

I was honestly, not sure of this book at first, there were times when I got really invested and others that I was as much, until about the 70-75% mark and then I was all in, I couldn't put it down. I'm excited for what more is to come.

I received a gifted e-arc from the author and am leaving my review voluntarily!

A DARK ROMANCE NOVEL
THE 'IN TREATMENT' SERIES
This book is everything you want from a dark romance. The desire,the need, the poor choices.haha. Everyone wants the man who will burn the world for you. Zayn would burn the world and thenbury it too for good measure. With I no spoilers,l would say that this book is the perfect fit for anyone, like me, who loves the man who will do anything to protect the woman he loves. This also has some thriller elenents that are sure to leave you .

In Your Head is a dark, atmospheric thriller romance that blurs the line between desire and danger that feels both intoxicating and unsettling. Set in the rain-soaked Pacific Northwest, the story follows Dr. Katherine Pearson as she navigates grief, buried trauma, and a past that refuses to stay hidden. The setting mirrors Kat’s internal unraveling perfectly. I can’t imagine how I would feel with the revelation that the death of someone dear to me was much darker than I imagined.

The relationship between Kat and Zayn is intense, complicated. Zayn’s obsessive, morally gray presence adds a constant psychological tension that had me questioning his motives. What I wouldn’t give to have a hot ex-Marine obsessed with me for YEARS. The spice is SO good.🤌🔥It’s generous but never overpowering; instead, it fuels their emotional connections perfectly.

What truly stood out was how seamlessly the romance, thriller elements, and themes of trauma and healing were woven together. This book didn’t lean too far in either direction, so it was a perfect, gloomy, rainy, dark, thrilleromance wrapped in an amazing gothic house of your dreams & designer heels.👠 After the first chapter I was fully invested in Kat and eager to see where her story went next.

If you enjoy dark romance or thrillers, congratulations, you get both! Even better, it’s the first book in a series, so that means we’ll get MORE!🎉 This one is absolutely worth your time.

Thank you so much K. Hollow for the privilege of reading your ARC!

I received a copy of this for my honest review

In this story our FMC comes to love on the house her father unalived himself in. She is a psychiatrist, who used to work for the state, but after a serial unaliver case and her father, she moved and started her own practice to see less aggressive patients. Our MMC lives just beyond that house , and actually is the gardener for it. They knew each other as kids when she would visit, but now that she is here, he isn't going to let her get away. She is afraid of opening up to anyone, and he carries some secrets that he's hoping won't matter as much if she is already in love with him

In Your Head pulled me in immediately. The prologue is both kismet-laced and deeply unnerving in context, and the opening chapters drop the reader straight into Katherine Pearson’s grief-hazed isolation with confidence. The decision to place her in the very room where her father died, paired with her self-diagnosis, emotional numbing, and subtle hints of suicidal ideation, creates a compelling and uncomfortable contrast with her professional identity as a psychologist. From the start, there’s a strong sense that something is off in the best possible way.

One of the most effective moments early on is the flower callback to the prologue. Kat’s instinctive decision to press it between the pages of her book without fully understanding why *chef's kiss*. That sense of déjà vu and subconscious recognition was beautifully handled and genuinely memorable.

That said, Act 1 struggled with pacing and emotional distance for me. Much of the early narrative relies heavily on internal monologue and sequential reporting—I did this, I thought this, here’s a reminder that I’m struggling—which caused momentum to stall. Rather than letting us see Kat through action, choice, and interaction, the story often tells us who she is, either through her own narration or how Bea talks about her to her. As a result, I found myself feeling oddly detached from her, despite the intimacy of the POV.

There are also noticeable gaps in where and when we’re allowed access to Kat’s life, particularly her professional world, which initially felt disorienting. I wondered if this was intentional, perhaps a way of positioning readers to observe only what Kat’s stalker can observe? However, the lack of early context clues about the intersection of Kat's work and her personal trauma made it harder to fully understand the roots of her nightmares, her fixation on death, or the depth of unease surrounding her living alone.

When Zayn’s POV enters the story, everything sharpens. Chapter 6 was a turning point for me and easily the strongest chapter in Act 1. Zayn feels fully realized, grounded, and purposeful, and through his eyes, Kat finally comes into focus as a more dimensional character. His chapters consistently felt more engaging, and the chemistry, banter, and tension between them began to feel earned once both perspectives were regularly in play.

Act 2 benefits from increased momentum. The danger escalates, the stalker threats clarify, and the dynamic between Kat and Zayn becomes genuinely compelling. Their irritation, attraction, and mutual pull are well done here. However, much of the plot and romantic tension resolves a bit too quickly. I found myself wishing certain moments had more time to simmer, while other scenes lingered without adding forward motion which created an uneven sense of urgency.

The final act is where the story felt most rushed. While the comeuppance and reveals are satisfying in concept, key moments unfold too quickly to fully land. Several revelations raised questions I wanted more time with, rather than answers delivered at speed.

From a craft/style perspective, the prose sometimes lacks rhythmic variation, leaning heavily into straightforward subject–action sentence construction, which occasionally hindered immersion. Dialogue formatting and pacing also made some scenes harder to follow, requiring rereads to reorient speakers and emotional beats. The story has all the right elements, but finessing the connective tissue between those beats would allow tension to fully build before release and draw the reader in deeper.

That said, In Your Head is undeniably compelling. It checks many of the boxes dark romance readers look for: an obsessive, morally gray MMC; psychological tension; kink-forward intimacy; and layered danger beyond the romance itself. Despite my challenges with pacing and immersion, I was desperate to know what happened next—to Kat, to Zayn, and to the secrets buried beneath her father’s death—and that speaks to the strength of the premise and the pull of the story.

TL;DR: An addictive debut with an intriguing premise, an excellent MMC POV, and genuine dark romance appeal—but uneven pacing and rushed resolutions kept it from fully delivering on its potential for me.

This story is a heady mix of moody atmosphere, slow-burn tension, and dangerously addictive romance that immediately pulled me in. It carries that same brooding, rain-drenched Pacific Northwest energy that made Twilight so immersive, but with a much darker, more mature edge. I connected instantly with Katherine as a main character—flawed, grieving, intelligent, and emotionally raw. And Zayn? He is every fantasy wrapped into one morally gray enigma: magnetic, skilled with his hands in more ways than one, and impossible to ignore.

After losing her father, Dr. Katherine Pearson retreats to the isolated estate where she once spent her childhood summers, hoping distance will help her process both grief and the lingering fear left behind by a threatening former patient. What she doesn’t expect is how deeply the past still has its claws in her. As she rebuilds her life and practice in this quiet town, someone from her history reappears—always present, always watching, always seeming to know exactly what she needs before she does.

Zayn is woven into Katherine’s world so seamlessly that it feels almost inevitable. Their connection is intense from the start, charged with unspoken history and unsettling devotion. His fixation toes an uncomfortable line between protection and possession, creating a constant undercurrent of unease that works brilliantly with the psychological suspense. I found myself questioning his intentions, Katherine’s perceptions, and even my own comfort level as a reader—and that’s what made it so compelling.

The romance is undeniably steamy, but it never overshadows the plot. Instead, the intimacy heightens the danger, blurring the boundaries between desire, control, and trust. Beneath the passion lies a mystery tied to Katherine’s father, secrets buried within the estate, and truths that slowly unravel as she digs deeper—sometimes against her better judgment. Katherine herself isn’t innocent or fragile; she carries her own darkness, which makes her reactions and choices feel realistic and earned.

By the final stretch, the story becomes impossible to put down. Revelations hit hard, especially those involving her estranged sister, and the ending left my heart racing and my jaw on the floor. This is the kind of book that lingers in your mind long after you’ve finished—haunting, provocative, and emotionally charged. If you love dark romance layered with psychological intrigue, obsession, and characters who live in the gray, this one is absolutely unmissable.

Dr Katherine Pearson has been through the wringer. She was working a dangerous case as a psychiatrist where a prisoner threatened his revenge on her one day. As if that isn't scary enough to always look over your shoulder, her dad passes away. Her dad was all she had left. Her mom passed in childbirth and she does have a sister, Rae, that she never sees. It's up to Katherine to head up to her dad's home where she spent her summers as a child.

What Katherine needed was this time away from her life. She sets up practice in town and she gets to start over. Until a man who looks familiar comes in as her patient. She immediately feels a connection which is a big no-no. She discovers its Zayn that used to live on the property with his family. He used a fake name to see her as her patient. That's not even the weirdest thing Zayn does.

From that point on she's fighting the palpable energy pull between them. He's the caretaker for her house. He had a much more complicated relationship with Katherine's father than anyone knew. His death had meaning and Katherine sets to find out what is being kept from her. She doesn't mean to uncover Zayn's dark secrets in the process. Katherine is quite dark herself. Will she accept his darkness or try to move on with life?

Good luck putting this book down! This is definitely a book you devour in one day. The ending will have you gasping and when truths are revealed about Rae, you may actually scream. Heart pounding suspense, wrapped with twisted and dark romance, sprinkled with obsession....that's how I would describe In Your Head.

I simply devoured every second of this book! Hollow’s command of prose, style, and story is superb and had me hooked from the moment I stepped into her world. Nothing feels overwritten, nothing feels out of place. This is what I yearn for in an indie debut!

I was swept away alongside Kat, moving from Seattle to lush, dreary, and eerie Greenwood, set deep in the Pacific Northwest where she reconnects with her obsessively protective stalker, Zayn. She’s a true black cat protagonist, and I loved how Hollow handled her trauma, healing, and her deep and dark connection with Zayn.

Zayn! ZAYN! Meet your new book boyfriend. I was obsessed with him by page 4. There were so many moments where I was questioning his sanity, my sanity, who was doing what to Kat, who he really is, his motives, on and on. He’s protective, obsessive, and more attuned to Kat’s needs and fears than she is herself. It’s almost like he knows her better than she knows herself - the perfect stalker.

The spice was generous and delicious AND plot-forward. Absolute perfection. The thriller beats were seamlessly woven into the story and I was questioning my own sanity, right along with Kat.

Kat and Zayn’s trauma, shared darkness, and deep twin-flame connection were gorgeous, romantic, and everything I want in a dark romance. The extra chapter, teasing the next book in her In Treatment series? Ughhh, I can’t wait! Thank you for trusting me with your ARC!

This book had me forcing myself to stop reading just so I could go take a shower, and that is saying something for me, because the blend of spice and suspense is that intense. It delivers all the moody, rain-soaked, Pacific Northwest atmosphere that made Twilight so addictive, while introducing Katherine, a painfully relatable FMC I fell for almost instantly, and Zayn, who is the living, breathing definition of tall, dark, and handsome and yes, he absolutely cooks, both in the kitchen and in the bedroom. Dr. Katherine Pearson, a psychologist, returns to the PNW after her father’s death, only to cross paths with Zayn, the groundskeeper’s son on her father’s estate and, unbeknownst to her, her long-time watcher, not in a creepy way but in a I promised your father I’d protect you, I’ve always cared, I always show up when you need me kind of way. He seamlessly weaves himself into her life, appearing at exactly the right moment, every single time, and the tension only coils tighter from there. Huge thanks to K. Hollow for the ARC; this one left me breathless.

Having become a romance reader for only the past year or so (thanks to the encouragement of my best friend) I have started to discover my preferences in the genre. Whether there is too much or too little spice. The difference between the character development that allows me to feel connected to the characters and those in which I cannot find that bond. Sometimes a story is leaning too heavily on the smut and not enough on the characters. I want the story to be just as good as the spice. This being said, I have begun to find my niche. IN YOUR HEAD is my niche. This book has just the right amount of it all. Katherine Pearson has depth and is someone I want to know and care for. She feels like a friend and I am absolutely rooting for her and have come to love her. Zayn is hot as hell and the urgency in his care and obsession with Kat is palpable. Their story unfolds in beautifully written ups and downs. There is darkness and honesty and growth. I enjoyed every page and I CANNOT wait to read Rae’s story next. That teaser chapter has me at the edge of my seat!

Thank you to the author for providing me with a copy. The following review represents my honest opinion.

OH MY GOD I ate this up in one sitting. I was so hyped for this book that I couldn't resist starting it the same day it came into my inbox. And let me tell you that it somehow managed to outdo the already crazy hype I had for it! This is one of the best dark romances I've read and I'm not even joking in the slightest. The romance is perfect, the banter is delicious, and there were some certain scenes that I ate up 🤭. The writing is gorgeous and Hollow has such a command over her words. I could have honestly read 600 more pages of this book and still wanted more, that's how good it is.

You can count on me wanting to read EVERY release by K. Hollow and I will 100% be in her DMs (already am tbh) screaming about how amazing this book is.

I don’t even know where to start with this book. Firstly it is my second ARC and I didn’t enjoy arc reading the first time so I was skeptical to apply for another ARC incase it happened again. IT DID NOT HAPPEN AGAIN. I couldn’t put this book down. Literally. I had to be up early to get ready today and I honestly said fuck sleep and stayed awake late to finish it. This book was hot 🔥🌶️🌶️🌶️🌶️🌶️ but not too much spice that it overrode the actual plot, which often tends to happen in spicy books. It was so beautifully written and honestly I’ve personally never read a book like it. I really really enjoyed it and I hope everyone else does too!! Thank you K for trusting me with your book 🥹🖤 it was perfection… YOU are perfection!

I’m thankful that I got a ARC reader for ‘In Your Head’
I devoured this book in one day and already can’t wait until the next one. I really enjoyed her writing style and it having a dual POV. Kat is a Psychologist who is battling her own demons and grief through the book. I loved watching her evolve throughout the pages. And Zayn, oh how I adored him and the way he is with her. There’s some people that are just meant for each other. I won’t say much else so I don’t spoil anything, but definitely worth the read. And the bonus chapter makes me pine for the next book in the series’s.

I was unbelievably honored to be able to participate as an ARC reader for In Your Head by K. Hollow.
In Your Head was a work of art! The setting in the Pacific Northwest made such beautiful imagery and added to the twisted (but relatable) mental and professional struggles of the fmc Kat. I was captivated from the very beginning and stayed on the edge of my seat until the end! For me, the suspense, danger, and the (DELICIOUS) romance made an intoxicating and addictive medley for the book—so much that I FLEW right through it.
I can’t wait to read more!

Smart & beautiful FMC: but make her mind dark & relatable.
Insta-love: but make it feel like a slow-burn.
Obsessive romance: but make it nurturing AF.
Spicy plot: but make it twisty and thrilling😮‍💨

This book was dark and twisty. Towards the end I thought I had it figured out but I was slightly wrong about one thing which was a good thing!
She was dark, she was spicy, and she has all the psychological elements that is dark romance.

I love how it asked the question of hard limits and what was going to be acceptable for Katherine and what she thought she could handle.

The bonus chapter had me all geared up for her sister’s story, which is coming next!

Kathrine is returning to the PNW after the death of her father. She's grieving and luckily has Zayn, the caretaker of her father's estate son. He's always watching over her, he's there whenever she needs him and it's so obvious that he's totally in love with her. Great read!
