How to Kill Your Biggest Fan

Rate this book
Bestselling romance author Hazel Witt has been writing for 20 years, has an army of loyal fans, and delivers sell-out events with every new book she writes.

But Hazel hates romance, hates her readers, and is completely disillusioned with the publishing industry. The only people she tolerates are her agent, Derek, who terrifies her, and her assistant, Ayo, who ferries her from one tiresome book signing to the next.

Despite past success, Hazel's sales are dwindling. Derek tells her she needs to write something different, and when Ayo finds a disturbing and obsessive letter from Hazel's biggest fan, Margo Martin, Hazel descends down a rabbit hole investigating Margo's past.

Margo has spent years being obsessed with Hazel – using her books as literal bibles, taking the events in her novels as dating advice, and believing that the characters within are real.

As Hazel searches for Margo, a cat and mouse back and forth ensues, with Margo seemingly one step ahead at every turn. Can Hazel escape the woman who has turned out to be a deranged stalker, desperate for love? Or does she need Margo more than Margo needs her?

Hazel Witt has been a best-selling romance author for over 20 years. She has her strong fan base which includes one (possibly) deranged fan named Margo that has written numerous letters to Hazel over the 20 years. Only Hazel didn’t bother to read them. That is until her assistant decides to open, let’s just say, Pandora’s box.

I love a book where the lead character oozes in snark! In the beginning, Hazel had me literally snorting in laughter. It tapered off somewhat as the book went on. If she could have upheld that level of sarcasm, this would have been a full five-stars for me. Still a very fun romp!

This is a debut from Helen Blair! And I’d definitely be queuing up for her next!

I hope this author was potentially writing a despicable, unlikable character I never rooted for, otherwise this book might be one star.

A disillusioned romance author hates her readers but relies on them for her career as life until a disturbing, obsessive fan letter starts a terrifying cat-and-mouse game with a (frankly crap) author who peaked with one series and her stalker.

Either this was meta and satire or I hate this book.

The writing was addictive and the prose truly beautiful at times. This was mix of genres and messaging, so that the final product feels wonky and weird. Almost jaded.

This is almost a critique on the perfect, happy romance genre, women’s lit fic, and a thriller. It failed on all accounts.

At times racist, ableist, ageist, and pessimistic. Also, a hate manifesto on the current branding of authors rather than their book and the insurgence of influencers, bloggers, events, and author engagement.

Whilst this could have been a satire, I don’t think the author manservant pull it off.

However, I loved her clever prose and use of language.

As a reader (and lover) of many different genres - when I'm asked what my favourite book is, it's a really tough one to think about and answer, without going on forever and listing many books!

But, every so often, a book comes along that contains so many of the different tropes I love, that I just have the best time - and this new release (and debut) is one of those books!

 

Lots of the these elements, I actually cannot talk about here because there would definitely be some spoilers!

But this book had me on edge, creeped out, cringing and laughing from start to finish and I loved every second.

 

Our main characters are certainly a pair who I felt that I shouldn't in fact like - both with fatal flaws - but I just couldn't get enough of them.

I loved the sarcasm, the disregard for social boundaries and that strength to take what life has thrown at you and to turn it round and just not give a f*** anymore!

 

I loved the way that the thriller storyline happening in real life, becomes the next big story for Hazel and the fact that this then becomes a story in a story in a story - making it hard to really work out what to believe.

What is real, perceived or imagined and just how reliable is our narrator?

 

There was so much going on from start to finish and I literally couldn't put this down - I even enjoyed the extra housework that allowed me to keep in listening to the end!

 

I cannot believe that this is a debut novel and I can't wait to read more from this new author.

In fact, I'm overjoyed to hear that there might even be a sequel coming soon - I cannot wait to be back with Hazel and Margo as they're certainly some of my favourite characters to spend time with.

 

This book is going up there with a few of my favourite other reads and I'll liken this to Death Of A Bookseller for amazing characterisation and Misery for content that had me gripped from the start.

Throw in a little shrinking of Sweetpea and Thelma and Louise and you've got a winner.

 

I absolutely loved this book so much - I might even go back in for a re-read to end the year on a high!

3.5 stars rounded up to 4.
Hazel Witt is a cantankerous washed up romance writer. Her latest book is flop, she is estranged from her family and is barely tolerated by everyone else…well except for one person. Margo is Hazel’s biggest fan. She has written her over 200 letters yet Hazel hasn’t read a single one. That is until her assistant brings the last letter to her attention - the last one Margo wrote before she disappeared. With the tables had turned, Hazel needs Margot and she delves into her biggest fan’s past, but will doing so ruin Hazel’s future?

I enjoyed a lot of the elements of this book and I would say Margo’s letters are the highlight, full of unreliable narration and eyebrow raising antics. It’s a good mystery and there is a satisfying character arc for Hazel. However it irked me that the author made her weight 50% of her personality when it didn’t really add anything to the book. The ending was a little anticlimactic. The narration is great, I loved the range of accents used to bring the book to life.

I would definitely recommend the audiobook overall, especially if you enjoy unpleasant but entertaining antiheroes.

Thanks to the author, publisher and NetGalley for a chance to review an advanced copy of the book in exchange for an honest review.

Thank you to NetGalley and Bolinda Audio for the ALC.

Plot 4.5/5
Characters 4.5/5
Ending 4.25/5
Interest 5/5

Overall 4.5/5

-I don’t often read these types of books, but I like to indulge in them from time to time. And this time, it was amazing. The fact that it was an audiobook as well really made me feel like I was part of the conversations and process of everything that happened in this book. The plot line was so intriguing and I could stop listening.

-The characters were so interesting, I liked how none of them were the conventional characters were see in every single book nowadays, especially all of the books I’ve been reading. Hazel had a lot of bagage which was so interesting to see throughout the book and some things being reflected to Margo. Margo was so interesting, we don’t actually see her until quite late in the book but she from the start she truly was intriguing.

-The ending shows how nothing can be perfect and nothing can be tied neatly with a pretty bow. There is still so much intrigue at the end of this book and there is still so much to tell but I am very glad with how the book ended so mysteriously.

Thank you Bolinda Audio and NetGalley for this ALC, coming January 1st.

This story grabbed me from page one. The pacing is sharp, the manipulation and mind games are addictive, and the dynamic between the characters is a delicious blend of tension, humour, and “oh no they didn’t.” I was fully entertained start to finish. Loved Hazel, the introvert writer who is detached almost from all the people. Margot got my interest and her story is heartbreaking yet she is multilayered character.

There were a couple of moments that pulled me out — especially one department-store scene with body commentary that felt unnecessary and didn’t add anything meaningful to the story. And at first, the ending had me blinking into the distance, wondering why we took that turn.

…But then I listened to an interview with the author and learned this is book one of a trilogy. Suddenly those choices make a lot more sense — you can feel the groundwork being laid for the chaos to come.

I also really enjoyed the narrator, she outdid herself.

ALC REVIEW

"After all, you can't kill someone who is already dead... Can you?"

Thankyou Netgalley for this opportunity!

I didn't know what to expect jumping into this audiobook I applied for the ALC on Netgalley on a whim as the title caught my eye and I was so glad i did.

What a freaking fun ride! It had on the edge of your mystery, it made me laugh out loud on nearly every page and revolved around 2 women with main character energy we love! LOVE Margo and Hazel.

I had the BEST time listening! The narrator absolutely nailed this one.

Keeping this review short and sweet because you absolutely have to experience it all for yourself! I recommend going in absolutely blind like I did, it made it so much better!

As a reader, and author, who isn’t much of a people person, who has a pet sausage, and whose life would be much happier lift within the confines of my house, I don’t think I’ve resonated to a book as much as I have with this one.

I’m not a regular thriller person, so there’s a lot in thrillers that surprise me, I’m not great with the twists and spend so much time overthinking to the point I plant myself on the wrong track every single time, but sometimes the thrill of the book is in the possibility that these scenarios could be real.

From a reader perspective - loved it! I think it was well written, the narration was absolutely amazing and bought so much soul to this book, and what an absolute ride for this poor author who just wants to release her books into the world and be spiteful about love in peace. This was very unique to everything I’ve read before, and so very relatable!

From an author perspective - new fear unlocked, in all honesty 🤣

Thank you so much to NetGalley, the author and Bolinda audio for the opportunity to read/listen to this book early.

How to Kill Your Biggest Fan is a dark comedic book festuring esteemed romance writer Hazel, who has become disillusioned with her books, and characters, in fact, with the entire romance genre. Unless she can come up with something fresh, her publisher will drop her. When Hazel's assistant Ayo uncovers one of many crazed letters from super stalker fan Margo, Hazel gathers a plan to dig into Margo's past and use it as her next novel. This dark rabbit hole unearths some disturbing truths and unleashes a dangerous cat and mouse game between the pair. It is deadly fun. #howtokillyourbiggestfan #helenblair #netgalley

READ THIS REVIEW IF YOU ARE CONSIDERING A DNF OF THIS BOOK—
I know I get it - the main character is INSUFFERABLE and not the good kind. This kind of insufferable that’s just being an asshole; judgmental and self centered.
I wanted to DNF almost immediately I could barely stand her but the story grabbed my attention and the audiobook narrator was fantastic so I carried on. I’m so glad I did- at about the 50% mark the author gave a nod to the reader- informing us that she knows the MC is unlikable. After that, I really started to enjoy myself. There were still a few jilting moments, one off the top of my head is the MC dropping the r-slur but I does fit with her character and unfortunately we live in a world where that’s still an insult. All of the characters were dynamic, troubled, annoying and realistic but also FASCINATING.
The author’s little nods to the reader were clever and made the unrealistic plot points bareable. After everything, this book took me on a journey and I actually ended up liking Hazel in the end 🤣

A psychological thriller laced with dark humour that ended up going in a very different direction to the one I‘d anticipated.
Helen Blair’s latest teetered on the brink of funny and something much darker, as grumpy novelist Hazel discovers (a little too late) that she has a stalk.. er, huge fan.
Margo has written to Hazel (who studiously ignores all fan mail) since her late teens, having discovered Hazel’s Teen Magazine romance column, the stories in which were turned into romance novels and Hazel’s career as a novelist was born.
Now, Margo is missing, and the collection of letters Hazel’s amassed from her over the years may help to find her. Meanwhile, Hazel’s writing career is floundering, and when her publisher tells her to switch to a new genre, with no thought for the consequences, Hazel decides to draw on her recent experience…
Susie Riddell’s colourful narration was entertaining and engaging. Five stars from me, with thanks to NetGalley and Bolinda Audio for the chance to read an ARC.
How to Kill Your Biggest Fan released on audio on 1 January.

Hazel Witt is a cynical and acerbic woman, nearing 50, estranged from her family, and clinging onto her career as a romance writer; once flourishing, but now flagging.
When her assistant Ayo comes across a letter from a fan (Hazel has decades of them in boxes, unopened), the cry for help finds Hazel looking to save a life, though it soon becomes obvious that it is just as possible that she might lose hers.
The genius of this book is Helen Blair's ability to unfold the picture of Hazel's deranged fan (done in such a way to evoke real pathos), while also taking Hazel on a journey of self-reflection. Is she that different to her stalkerish fan? Has she actually disconnected herself from reality?
I would say that my only issue with this book is that I hoped that the journey of self-discovery would lead to more growth. In the end (I'm trying not to drop spoilers here) I ended up feeling like there was too much narcissism, and the whole book was a little bit of an ode to the cruelty of lives that are lived without any real empathy.

With all that said, it was a cracking story, lots of great twists, and I enjoyed every moment of it!

A twisted cat and mouse thriller with tongue in cheek, laugh out loud moments.

When a jaded and disillusioned best selling author reads a letter from a fan that indicates they may be considering ending their own life, Hazel is convinced (or justifiably pressured), to look into it a bit more. Only to find that this letter is one of many, (and I mean many!) from Margo, her self appointed, obsessive, number one fan. Unravelling Margo’s life through her letters which read like a dark and twisted diary, Hazel is suddenly thrust into a game where she always seems one step behind her deranged fan girl.

I listened to this as an audiobook and thought the narrator encapsulated the characters brilliantly.

I received this book from the digital distributor and all opinions are my own.

The plot was entertaining and kept me hooked, even when things started going a little off balance. The shift between storylines felt patchy at times, and some transitions did not land as smoothly as I would have liked.

What stood out was how unhinged the narrative became. The way an entire life is uprooted, reshaped, and then treated as something disposable by the end was disturbing in the right way. The book does a solid job of showing how a psychotic mind works, covering multiple angles of obsession, following, and the willingness to do anything when someone or something comes in the way.

One idea discussed through Hazel really worked for me. Pure romance rarely does much on its own. It needs to be layered with fantasy, mystery, or historical drama to truly take root, and this book clearly understands that.

Recommended for readers who enjoy psychological tension and for fans of Kary Brent, as the themes feel very similar.

The humour of Sweet Pea and the dive into the publishing world books such as Yellowface gave us, I could not stop listening to this book and I cannot recommend it enough. How to Kill your Biggest Fan follows bestselling romance author Hazel Witt who has been writing for over 20 years and in doing so has generated an army of loyal fans, however, Hazel herself hates romance, hates her readers and doesn't have many positive things to say about the publishing industry. When Hazels agent tells her that she needs to write something different and her assistant finds a disturbing and obsessive letter from one of her biggest fans, Margo Martin, Hazel find herself down a rabbit hole investigating Margo's past and as things progress Hazel begins to wonder if she can escape the woman who has turned out to be a deranged stalker.

I was obsessed with this book and utterly hooked. Hazel is not your predicable likeable FMC. She's moody, snappy, harsh, not very kind, sarcastic and a little complicated but the more I read this book the more I took to her and the more she began to feel like a normal, imperfect woman I couldn't get enough of. At times I wanted to shake her and loosen her up, tell her it was okay to take a step back and let people in but I also totally understood her and why she was the way she was, accepting Hazel for being Hazel. This a FMC perfect for those who loved Rhiannon in the Sweetpea books for I found they were very similar; both fairly unlikeable and actually rather funny. The humour in this book was way more present than I was expecting after reading the synopsis, I found myself loving the dull, dark and very British humour that lasted throughout this book making Hazel even more relatable and at times even a little likeable. As for Margot, this was a character I found myself totally invested in. Her letters to Hazel felt as though they were coming from a real teenage girl with her problems, thoughts and feelings all coming across so real and relatable. She was a character so perfectly written and with those letters feeling so personal it was easy to see the natural progression of her character and why things went the way they did and the decisions she made. Her utterly unhinged behaviour shocked me, appalled me and had me so entertained! You gotta love a far from perfect female character. This was a woman who started out as a girl who needed someone to talk to, needed to escape and also needed someone to blame and found all of that in Hazel and while she lost herself and became so deeply unlikeable you still emphasised with her and wanted her to find peace.

This was a clever, entertaining and well written book and it must be said that the narration was perfect. The narration for this book was truly incredible, Susie Riddell did a fantastic job at bringing these characters to life and making Hazel feel like a real person. I felt as though I was truly in the minds of these characters thanks to the emotion Susie was able to showcase without over doing anything. She made it easy to listen to even at a 3x speed and with no over exaggeration I was able to still feel the emotion and the natural pacing of the book.

I loved how How to Kill Your Biggest Fan showed us a side to not just the publishing world but the life of an author and how complicated, personal and obsessive it can be. Seeing Hazel get lost in this dive into Margot, the impact of her books on her fans and the darker side to the industry left me hooked and I would recommend this to anyone who loves a book with a few twists, an imperfect FMC and true British humour.

Hazel Witt used to be a successful romance writer; unfortunately, her star is on the wane. She also dislikes having to engage with her fans. When a letter from her biggest fan, Margo, hints that she has taken her own life, Hazel digs into the past and discovers hundreds of letters from Margo, letters that display disturbing behaviour and give her an idea for a new novel.

I do enjoy the new breed of modern stalker novels, the dark humour, contemporary setting and unreliable narrator all appeal to me. Recent books in this sub-genre that I've loved at Cuckoo by Callie Kazumi and Julie Tudor Is Not A Psychopath by Jennifer Holdich. It's no wonder that How To Kill Your Biggest Fan by Helen Blair leapt out at me.

The main character, Hazel, has been writing romance novels for twenty years, which has allowed her to live comfortably, avoiding interactions with people in general. She's well aware that she has to keep her fans happy by doing book signings and guest appearances, but she avoids these as much as possible and certainly doesn't do anything beyond the basics.

I loved the way that the author poked fun at everything involved in modern-day publishing, from book signings through to podcasts. The story is filled with satire, and it certainly will make you ponder the next time you're at any kind of author event.

When Hazel's assistant uncovers a disturbing letter from Margo Martin, a young woman who's been a fan of hers since her early years as a magazine writer, they become concerned about her well-being. Discovering hundreds of unread letters from Margo in which she pours out her heart, and some of the terrible things she's done, gives Hazel an idea for a brand new book, something completely different. However, as Hazel digs into Margo's past, it becomes obvious that someone is watching her. I was completely engrossed; the storyline flowed perfectly. Not only was I interested in Margo's backstory, I also found myself worrying about Hazel's safety and the identity of the mystery watcher. The narrator, Susie Riddell, did a brilliant job at building the tension as all three stories eventually converged, with a conclusion that leaves you satisfied, but chuckling.

This is only available in audiobook format currently, hopefully that publishers will release it in paperback or ebook soon.

after all, your readers could never hurt you—could they?
bestselling romance author hazel witt has spent twenty years building a glittering career and a devoted fandom. margo is one of them—a fan who has mistaken fiction for entitlement. margo has been reading hazel’s books as scripture rather than storytelling. after decades of unread fan letters and unanswered admiration, she no longer wants just recognition but so much more. margo is ready to step into the story itself and call it her own, even if that means stalking, blackmailing, and threatening the very author she once adored.

if there were only one audiobook i could forever recommend, it would be this. case closed!! it thoroughly consumed me. a story within a story. the narration. the characters. i am obsessed!!

this is a novel acutely aware of its own audience. it understands the intimacy of reading, the false closeness it creates. hazel, gloriously self-absorbed, is buffered by success, and margo is unhinged as a fan, her fixation growing from loneliness and longing.

the satire lands because it trusts the reader. helen infuses humor that is dry and blunt, exacting with cruelty, and steeped in the mind of a sociopath—something only those in reading culture and fandom can fully appreciate. when hazel and margo are finally forced into direct confrontation, author and fan collapsing into the same space, it interrogates the power dynamic but refuses to bend to the ease of moral clarity. in my opinion, there is no singular antagonist here, only an anti-hero and an author locked in a stalemate, sure there is a huge difference in the gravity of their actions but blair makes room for empathy on both sides. she makes sure, we know that the protagonists, are both very unlikeable but also let’s us understand not just what each woman does, but why she does it, shaped by the pressures and silences that push them into a corner.

like anti-hero playing beneath the text, the story keeps reminding you that the problem is never just one person.

how to kill your biggest fan commands attention from its opening line and sustains it without faltering.

This was an unconventional mystery book I have read. It's different from the cookie-cutter thrillers I have read, where the readers are on a quest to find the killer. This is more like a wild goose chase, where an abrupt fan letter from Margo to Hazel starts the mysterious chase. Hazel, the MFC, is the author who is famously known for writing romance bestsellers, but hates romance in general.

I was hooked on this one from the first chapter. I love Hazel's hilarious internal monologue. Margo seems a bit dense to me, as I felt she was cadging men to have a better life, which is ridiculous 😳. I mean, yeah, a responsible man is a good one to be with, but to see affluent men as a medium to lead a comfortable life is something very shallow of a thought to me. Again,she has her reasons (read the book)

The letters Margo wrote to Hazel were like a series of a teenage life to adult life she's sharing with her unknown BFF/confidant, whose books are like a life guide for her, and yeah, why not, she's Hazel's biggest fan eventually.

Now comes the detour, where Margo is in London chasing Hazel, only to threaten and kill her. I felt this part of the book was a bit obscure. The book also highlights the dark side of the escort business. This book gave me a Katy Brent's book vibe.

Hazel, undoubtedly, is my favourite character in this book, because managing a psycho stalker, a disgruntled employee, a niece, and a bunch of snotty publishing professionals is truly the freshest of hells. (This is a line from the book. Surely this book improved my listening skills, beautifully narrated by Susie Riddell

I didn't anticipate the ending to end up a cliffhanger. Why 😭?Margo surprised me in ways I can't fathom 😮. Not giving out much but you will be left bedazzled. All in all this is one of the most immersive audiobooks I have listened to.

Mystery fans with a love of the quirky will find much to enjoy here.

My favourite quotes 😍
🧡Truth is always stranger than fiction.
❤️A woman's favourite flower is privileged information
🩷It's best to be on your own. People are such dreadful liabilities.
💛A wedding ring is not a magic wand, it won't protect you from infidelity, illness, debt, hormones, addiction or tragedy in the years that follow. There's no escaping it.
💙Life is just as hard, whether you're single, engaged, married, divorced or whether you have kids or choose to be child-free. Every choice has a consequence. Things will happen that are outside of your control, the best you can do is ride the storm and look after yourself.

“How to Kill Your Biggest Fan” by Helen Blair is an irresistibly twisted delight. It is a darkly funny, compulsively listenable story about two women you definitely wouldn’t want to grab a coffee with. Hazel is gloriously self‑absorbed writer, while Margo her fan is, frankly, just unsettling. Both women drag behind them more emotional baggage than they would ever care to admit and old wounds as well as their tangled histories get revealed as layers are peeled back.

Blair’s concept feels fresh, original and gleefully over‑the‑top in the best way, yet the emotions at its core ring true. Her writing is razor-sharp and wickedly funny; it made me laugh out loud even as the story slid into sad or even genuinely creepy moments. Every side character feels alive, like they’ve wandered in from their own novel, adding texture to a world that’s both absurd and painfully human.

And Susie Riddell’s narration? Spot‑on. She captures Hazel’s acid sarcasm and Margo’s eerie intensity with perfect precision, balancing humour and tension with effortless timing. Her delivery amplifies Blair’s wit while grounding the emotion, making the whole experience utterly addictive.

Brilliantly written, darkly comic and full of heart — Blair’s novel is clever escapism with soul and a wicked glint in its eye.

Thank you to Bolinda Audio, NetGalley and Helen Blair for an advance listening copy of the book.

"How to Kill Your Biggest Fan" by Helen Blair is an absolute thrill that I flew through!
The author struck the perfect balance between a fun, engaging plot and high-stakes, heart-pounding moments that kept me on my toes from start to finish.

I absolutely loved the storyline. It’s the kind of book that grabs your attention and doesn’t let go, filled with truly heart-pounding moments that had me completely invested in the outcome. The suspense is handled exceptionally well—it’s not just a slow mystery but a fast-paced ride that makes you want to uncover the truth as quickly as the characters do.

One of the best parts was the ending. Often, endings can feel a bit rushed or unearned, but this one left me feeling genuine excitement. It felt like there could easily be a sequel, and I’m already looking forward to the possibility of returning to these characters.

Overall, this was a fantastic, high-energy book. I listened to the audiobook narrated by Susie Riddell, and you could really feel a connection between the narrator and the characters. She delivered a delightful listening experience!

If you want something that is both entertaining and suspenseful, I highly recommend picking this one up!

I am quite impressed! I did not know that this was a debut book which makes it even more amazing by how well it was woven together into a twisty tale of love stories, authors, stalkers, and I never quite knew how it was going to end up! I loved it though, despite the main characters being quite prickly and also probably crazy (but quite clever). And it made for a great audiobook as well!

Hazel Witt is what I would call about burnt out as an author, writing happily ever after love stories but not finding much happiness in real life. Luckily, or unluckily a letter from Margo Martin shows up to liven it all up and chaos claims it all! Between Hazel's search for Margo and Margo's letters, I was completely entertained and intrigued as I tried to figure out what was true, what was embellished, whether there was a case for unreliable narrator, and if Hazel was going to make it out with a book to sell or if Margo's obsession was going to be the death of her!

Great story and audiobook! The narrator, Susie Riddell, did a great job of bringing the characters to life and their sordid tale of loves lost and audience pleasing books written and a few dead bodies along the way. I am looking forward to seeing what Helen Blair will come up with next!

Plot wise this book was great. It was entertaining and kept me engaged but I was a bit put off by the random inclusion of internalised fatphobia?

I understand not all characters will necessarily be likeable, and nobody is perfect so flaws make them more realistic but I feel like we got introduced to the fact that Hazel is fat quite far into the book, out of the blue, and then comments about her size then kept happening at random - the whole scene in selfridges was not needed and added nothing to the plot and even at the end the comment about not being hungry for the first time in her life was just weird and uncomfortable. It didn't serve the plot or characterisation in my opinion. What it did do was feel reminiscent of the way media was 20 years ago, when everyone had to know how bad being fat is and we must make people strive to be skinny. It just felt really jarring and shoehorned in and I cannot fathom why and for that the book lost some stars. I'd honestly be inclined to give it just 2 stars but I felt that was perhaps me being too harsh and too critical of it so I've stuck with 3.

Thanks to Helen Blair, Bolinda and Netgalley for a complimentary e-audio arc of this book in exchange for an honest review.

I almost dnf'd this book in the first 50 pages but by gosh, am I glad I did not! Our main character, Hazel takes a bit of getting used and for this first portion of the book I found her to be quite unpleasant but as the book carries on thankfully we learn more about her and why she is so jaded and antisocial, why she had such an attitude towards the world around her, and she also starts to change herself and grow into a more caring person.

This book was absolutely WILD also, and I had so much fun with the wry humour and the genuinely terrifying character of Margot in this fun tongue in cheek thriller which pokes fun at the romance genre and publishing in general! I find it hard to believe this is the authors first book as it is brilliantly paced and plotted for a debut! I also thought the audio narration was perfect and really fit the tone of the book and the characters of Margot and Hazel perfectly. I also really appreciated the lgbt representation we got in this book with some of the cast.

Romance author Hazel Witt, has dwindling sales and her agent tells her she has to try writing a different genre, say a murder mystery.

She comes across letters from her biggest fan that have been unread and gathering dust for years. As she reads the letters it’s obvious her biggest fan, Margo, is an unhinged stalker who blames Hazel for the turn her life took. This gives Hazel an idea for her new book, which she begins to write as she also searches for Margo, who always seems to be one step ahead of Hazel.

The premise is a fun one. The MC’s thoughts are witty & snarky. At first.

As far as I can tell, this title is released only on audio. At nearly 13 hrs long, it felt interminable. The sections where Margo’s letters are narrated were too long and boring with unnecessary details. I zipped through large portions and missed nothing,

Hazel increasingly grew unlikable and the book had an identity crisis. Is it a murder mystery, a psychological thriller, or a comedy? The tone felt off for a psychological thriller, and the humor felt misplaced for a thriller. I lost interest in both.

The narrator of this audiobook is good. Their voice and accent fits with the story.
I like the beginning of this book. It’s interesting watching the author discover the letters and try to figure out more about this fan.
It was engaging and made me want to keep reading. I did want to learn more about Margo and what had happened to her.
Part way through, the book feels like it stops. Most of the plot is the letters and the main character doesn’t really do anything in present day. A lot of the things that happen in the main character's life feels pointless. The ending dragged on and I lost interest in what was happening.
The main character is annoying. It starts as just flawed, morally grey, but it quickly devolves into unlikeable. It’s annoying to see her judge everyone for the smallest things.
The whole book is a bit too meta for me. Making fun of the romance and thriller genre. Something I know some people would enjoy, but not for me.

I was a huge fan of this "FAN" book.
👏👏👏

WHY?
❤️ I adore unhinged, deeply flawed, plus-sized female protagonists.

❤️ The author's nonstop snarky wit was unsurpassed.

❤️ The book was compelling, pacy, and refreshingly different.

❤️ This darkly funny, pulse-pounding tale of obsession, stalking, suspense, and what happens when an author pivots genres was absolutely, positively brilliant.

A very, very impressive debut by author Helen Blair.

I listened to the audiobook, expertly narrated by Susie Riddell.

Susie Riddell perfectly embodied the protagonist’s traits and quirks, capturing her personality and voice spot-on.

Special thanks to NetGalley and the publisher for an ARC in exchange for an honest review.

All the stars!

One of my besties of 2025!

Hazel is a writer who doesn't read fan mail.
Margo is her biggest fan who has been sending letters for years even when she does not get a response.
When Hazel is shown one of the disturbing letters, she goes down a rabbit hole to find out more about Margo and locate the rest of the letters.

Margo is deranged, has not had the greatest childhood, and plays games with people.
Hazel does not like people, and absolutely abhors 'sprayed edges'. She deducts imaginary tips she would have never given, and even when demanding for help knows full well that if the situation was reversed there's no way she'd help.

I enjoyed the mystery of trying to figure out if one of them was going crazy, and learning about Margo through finding her letters.

I really liked the narration by Susie Riddell. There is a behind the scenes chat with Helen Blair & Susie Riddell at the end of the audiobook. They talk about the inspiration behind the book and I think it adds so much to hear about how the characters and story developed.
