“Pretty much the platonic-ideal beach read.” —Ada Calhoun, New York Times bestselling author of Crush

Hello Beautiful meets Miranda July in this sexy, darkly comedic literary novel set in San Diego about an obsessive love affair that ends in a murder

For Perdita Jungfrau, a social worker who thought she was going to be married to her husband forever, falling in love with her anarcho-Marxist roofer Nando is a crisis. Every possible obstacle is in their Nando is fifteen years younger and has a girlfriend. Perdita is pregnant and terrified to mess up her children. None of that hinders her from being drawn to this magnetic man who entrusts her with his deepest secret.

Three years later, Perdita’s lover has been murdered. As her bewildered husband tries to make sense of the wildly unpredictable person his wife has become, Perdita has other things on her mind. For starters, who is the mysterious woman sitting outside her house in a parked car all day? How can she stop her adored baby brother from being pulled under by his opioid addiction? Can someone with a childhood like theirs ever be the mother her children deserve?

And most of all, what should she do with the searing memories of the affair, which turned her life upside down?

(Thanks to the publisher for sending me a copy of this book!)

I approached this novel slowly, as I wanted to fully absorb its ideas and narrative choices. The premise is definitely intriguing and was what initially drew me in. In particular, the author’s approach to the mystery feels refreshingly unconventional, offering a perspective I have not often encountered in similar works. That originality, in itself, I feel like is one of the novel’s strengths. However, the book did not fully align with my personal reading preferences, though I can easily see it resonating with a specific readership and being well received by many.

For me, the pacing felt uneven, often leaning toward the slow side. At times, several chapters came across as transitional or filler-like, with the central premise only truly coming into focus on a handful of occasions. I also struggled to form a meaningful connection with the characters, which likely contributed to my sense that the narrative occasionally dragged.

Nevertheless, the novel does succeed in delivering moments of drama, which provided a compelling element and offered something to stay invested in.

Wow, what a ride through mental health awareness this was. The main character tells a dual timeline story through multiple POV as her internal perspective shifts through different emotional lenses. Perdita is insightful and therapeutic even while her life is messy and chaotic at times. I kept changing who I thought the killer was and then circled back around.
The book took me by surprise, challenged me to think more deeply about mental illness versus internal conflict, and moved me as I reflected back on it.
Thank you, Summit Books and NetGalley, for the ARC and opportunity to provide an honest review.

This. Was. Messy.!!!! In the best way lol! What a crazy time line of events - although I know this totally unfolds in real life - the main character shares open and real thoughts about parenthood, having an emotionally distant husband, a brother struggling with addiction, and a never-present dad turned Monk in his later years of life while having an affair with the roofer her neighbor hired for work. If you are into family drama, secrets, “who done it” murders… this one is for you!

Cassandra Neyenesch’s A Little Bit Bad is one of those novels that slips a hand around your wrist and pulls you into a life already in motion—messy, magnetic, and impossible to look away from. At its centre is Perdita Jungfrau, a woman who has spent years trying to be good, sensible, and predictable… until she isn’t anymore. What begins as a reckless, intoxicating affair with Nando—her neighbour’s anarcho‑Marxist roofer, fifteen years her junior—spirals into a tangle of desire, guilt, and self‑reckoning that feels startlingly human.

The book moves between the heat of their affair and the cold aftermath: Nando has been murdered, Perdita’s husband is bewildered by the stranger his wife has become, and Perdita herself is juggling motherhood, grief, and the slow‑motion collapse of her younger brother to addiction. Neyenesch writes these tensions with a confiding, conspiratorial tone—almost as if Perdita is whispering her worst impulses to you over a glass of wine.

What makes the novel so compelling is its emotional duality: it’s sharp and funny in places, then suddenly tender, then quietly devastating. Perdita’s voice is charismatic, flawed, and painfully self‑aware. She’s not always likeable, but she’s always alive on the page. And the mystery—who’s watching her from the parked car outside, what really happened to Nando—threads through the narrative with a slow, simmering unease.

This is a story about desire and consequence, about the versions of ourselves we try to bury, and the ones that claw their way to the surface anyway. It’s messy, bold, and surprisingly moving—a novel that lingers like the echo of a confession.

3.5 stars

Thank you to Netgalley and Simon&Schuster for early access to this book in exchange for my review.

I absolutely loved the premise of A Little Bit Bad. A suburban housewife, an obsessive affair with her neighbor’s much younger roofer, and a murder hanging over everything? I was in immediately. The setup is sharp and darkly funny, and the tension starts early and never really lets up.

The mystery surrounding Nando’s death is genuinely compelling. The pacing is quick without feeling rushed, and I kept wanting to read just one more chapter to see how it would all unravel. The writing feels confident and controlled, especially in how it layers the affair, the family drama, and the looming question of who killed Nando.

The character development is also a major strength. Everyone feels real and complicated. Perdita’s husband, her brother, even the side characters all feel fully formed. Their flaws and motivations make sense, even when they hurt to watch.

Where I struggled was with Perdita herself. I appreciate an unlikeable or morally messy main character, but I had such a hard time connecting with her. Her choices felt chaotic in a way that frustrated me rather than intrigued me. I didn’t need her to be perfect, but I needed something to hold onto emotionally, and I just never quite found it. It made it difficult to root for her, even when I understood the pain driving her decisions.

Overall, this was fast paced, bold, and undeniably readable. I was hooked by the mystery and impressed by the depth of the characters, even if I couldn’t fully get behind the protagonist. A solid 3.5 stars for a story that kept me turning pages, even when it made me want to shake the main character.

Not 100% sure how to feel about this one. Let’s start with the murder mystery aspect, which I thought was good and surprising once the killer was so matter-of-factly revealed. I enjoyed the buildup and evolution of the main characters relationship.

Interesting delve into all sorts of psychotic thoughts and behaviors. Especially of Perdita, the main character who is actually a social worker as her occupation. The mantra of do as I say, not as I do ran through my mind as the novel progressed.

The story was a quick, beach read that sucked me in. I had the biggest problem with the threads of antisemitism woven through which were cast upon the “bad guy” Nando’s girlfriend. When an author feels free to perpetrate antisemitic tropes (describing the girlfriends father as a rich, Jewish Hollywood type, the top 1% of money) and foster extreme leftist viewpoints (Nando and the mother in the kitchen talking about the problems with Israel) that’s where I have to call this author out. If these viewpoints had been edited out (the author talks about the extensive editing process - I can only imagine what other vile viewpoints were left on the cutting room floor), I would have thought it was a much better book.

So 2 stars for the mystery, maybe another round of editing before release date. Or at least just keep your antisemitism to yourself.

I want to begin this review by saying a huge thank you to the team at Penguin Figtree for sending me this proof copy of A Little Bit Bad in exchange for a totally honest review.

I honestly found this book to be so unique, engaging and riveting. I couldn't put it down. We are introduced to Perdita, a mother and a wife. Her characterisation was absolutely perfect, and I just couldn't figure her out, which added an immense layer to the mystery of the book.

I thought that the way in which Neyenesch approached the mystery element was very unconventional and this made for great reading. I spent the entire novel trying to figure Perdita out, understand what was going through her head and process what was happening.

It felt so unbelievably refreshing to read a mystery novel that was unpredictable. This novel did not follow conventional storylines, plot changes, characterisation and tropes that would be expected in a novel of its calibre and yet, I found myself feeling at home in the book and desperately wanting to uncover what had happened to Nando. The book left me feeling on edge, at times uncomfortable, and quite frankly disturbed, but in the best and most controlled way.

An absolute raging success for me and one I will be recommending to all mystery lovers.

A Little Bit Bad is out June 4th.

Perdita is married to a man who doesn't appreciate her or proactively care for her or her children in any way, and she's grown to loathe him. It's no wonder that she falls for the contractor, Nando, after he falls, literally, from the roof. As she rushes to help him and call an ambulance, he maintains his wit and charm through a bloody face; he sees her, when it is he who is most in need.

I received an advanced review copy of this book from the publisher and enjoyed the narrator's voice right from the beginning. I read the first third of the book extremely quickly. We flit back and forth between present-day Perdita, who is fretting over the unknown details of Nando's recent murder, and past Perdita, who is pursuing an affair with this man, and at first these transitions are deliciously frustrating — just as it starts getting somewhere, we flash forward or backward, and we have to return to the previous mystery before we can move forward again. It starts to slow down after the first few chapters, however, and it takes a while before the action picks back up again. If you're looking for a slow and poetic "true crime" fiction, this one's probably for you.

Wooo-eeee, this was a wild one. At no point in time did I know where this book was headed. A Little Bit Bad stands apart because of its ability to combine genres in an authentic way. Neyenesch writes in a way that feels personal and real, almost like you’re inside the main character’s thoughts. The story doesn’t try to make anyone completely good or completely bad, which makes it feel more realistic and relatable.

What makes this book unique is how much it focuses on the character’s inner struggles, but also the way that she's an unreliable narrator. You're on your toes for the entirety of the story, and you won't able to exactly pinpoint why until the end. The female main character is just a little off-putting, and the power of the story comes from the small details.

My only complaint comes from some of the writing being a tiny bit stereotypically "edgy" to me. While most of the book is written in a way that's incredibly relatable and thought out, some random lines will sneak their way in that make me roll my eyes a little, mostly in relation to the romance aspect. But that very well may just be me experiencing post art school PTSD.

Overall, A Little Bit Bad is a novel with a strong literary voice and a plot line that makes it different from typical contemporary fiction.

⭐️⭐️⭐️ (3/5) – A Little Bit Bad by Cassandra Neyenesch

A Little Bit Bad had an intriguing premise, but my overall experience landed somewhere in the middle.

The concept itself has potential, and I can see this working better for readers who enjoy character-driven stories and don’t mind a slower burn or a protagonist who’s hard to root for. This is also great for readers who love satire/humor in their thrillers. While it didn’t completely hit for me, it wasn’t a bad read ,just not a standout.

My biggest struggle was the main character. I found her frustrating in ways that made it hard to fully invest in her story. While I can appreciate flawed and morally gray characters, her choices didn’t always feel compelling enough to keep me engaged.

I also found parts of the plot to be predictable. I was able to anticipate several key developments fairly early on, which took away some of the tension and impact as the story unfolded.

Thank you to Cassandra Neyenesch, NetGalley, and Simon and Schuster for the ARC in exchange for my honest review.

First, thanks NetGalley for a copy of this title in exchange for my honest review.

I am a little at a loss for words on how to accurately explain my thoughts on this book. From the beginning, I was intrigued by the chaos, and also by the voice of the man character. It really felt like I was stepping into her head. But at the same time, I was unsure about where the story was heading. What was going to be the conflict that needed resolving?

I found myself getting frustrated with the pace because I wanted to have more direction. I couldn’t tell what was filler, what was integral, or what was in between.

However, around the 80% mark, I felt the shift. And I realized that (I think) it was all intentional. While I loved the characters voice from the beginning, I felt myself stop trusting it. And, without spoilers, I fully understand why that shift occurred. And I began to appreciate that the author took me on the exact ride she wanted to take me on.

I am glad I pushed through some slowness to get to the end of the book.

This novel follows Perdita Jungfrau — a married woman with a child — whose life takes a dramatic turn when she falls in love with her much younger neighbour, Nando, a roofer who already has a girlfriend. What begins as an affair slowly unfolds into something far more complex and destructive.

The story moves between present time and past events, gradually revealing how everything spiralled out of control. The short chapters make it an easy and fast read — I finished it in three days.

What worked for me:
• Engaging pacing
• Emotional tension
• Strong central conflict

What would have made it a full 5⭐:
I would have loved more suspense and mystery surrounding Nando’s death. While there are twists toward the end, the “who killed him” element doesn’t feel like the driving force of the story until much later.

Overall rating: ⭐⭐⭐⭐ (4/5)

I have received an advance review copy for free, and I am leaving this review voluntarily.

Perdita plans to be married forever. Then in walks Nando, the neighbor's roofer. They begin an affair. But that's not all. He has a girlfriend, is much younger and oh yeah, Perdita is also pregnant. Then as if that's not enough, Nando is murdered. Messy, messy, messy. Okay, and super-fun! As a long-time old married lady with no plans on having an affair, the author did a good of making me understand where Perdita was coming from in her questionable choices. We also see her struggles with guilt and wanting to be a good Mom for her children. But enough about all that! We get a fast-paced and twisty story told in a way that felt different and fresh, a lot of cool characters and even something in there I didn't see coming! I am excited to read more from Cassandra Neyenesch!

Perdita is 40 years old. She’s married with a toddler. The prime of her life seems to be over and now things aren’t fun anymore. Being a mom is all consuming and her husband doesn’t help much. Sound familiar? She’s sick of it and trying to figure out what to do. They had five good years together but now it just feels like they are stuck in a bad spot. She meets the hot young roofer and has an immediate connection. She’s trying to decide whether she should blow up her fairly normal stale life. I LOVED this book. I love dark comedies with quirky characters. I also love thrillers but get tired of reading the same old stuff. I was so hooked on this book and these characters that I was blindsided as the events of the book happened. I can’t say enough good things. Go read it!

Wow! This was one of those books you’re reading and screaming “ Yes! This is fantastic!” the whole time. It’s funny (Hilarious) and relevant and touches on so many things in a woman’s life and loves. Cassandra Neyenesch is an exciting new voice. Straight to the point and unguarded. Voicing thoughts I’ve had before that I never dreamed someone else was thinking. This story is many things. Most of all it’s a great read. I predict this will be one of those books everyone is talking about. Read this and enjoy the ride.

Holy. Shit. HOLY SHIT. This book was twisty, sexy, fun and dark.

85% of the way - that twist. UNBELIEVABLY GOOD. So well-executed. It was like a really elaborate, sick and interesting ending to a movie where they explained who did the crime and how they got away with it. Wow Perdita was interesting and unlikable but so insanely compelling.

I did not enjoy this book. The characters are not relatable or enjoyable for that matter. Perdita makes some very questionable choices and is just over all messy. The ending did shock me, I did not see that coming.

Love the description of this book on the surface. I did find it rather amusing in parts but just didn't really care for the protagonist's story or her messy life. Sure she makes lots of questionable choices, fine we all do at times, but this one just dragged along for me. I found myself wishing it was a bit more suspenseful. Thanks to NetGalley for the ARC.

Spent my day reading this one. Obsession, affairs, and daily life.

I felt for the main character and her life. A little too long. I know life changes for many people, but sometimes you need to just move on from a marriage or work it out.
