Maybe it’s the charmingly girlish cover art; maybe it’s the fact that the author is only 29 and radiates cool, effortless energy in every photograph; maybe it’s because it was deemed an “internet novel” and sparked a lot of opinions—Lost Lambs by Madeline Cash took hold of the bookish It-Girl community as soon as it hit shelves in January. It even received the title of 2026’s buzziest debut. After all the hype online, I traversed to my local Barnes & Noble to get my hands on Lost Lambs before I was exposed to any spoilers, and thank god I did. I went into it having no idea what I was getting into, and I couldn’t have predicted how the story unfolded: It surprised me at nearly every turn. Here’s my full review.
For the three Flynn daughters, it’s been disastrous since their parents opened up their marriage. Casting a shadow across their lives is Paul Alabaster, a nefarious local billionaire. Rumours of corruption circulate, but no one dares dig too deep. No one except youngest sister Harper, whose obsession with Alabaster’s machinations sends the family hurtling into a criminal conspiracy–one that may just, finally, bring them closer together.
What is Lost Lambs about?
Lost Lambs combines a number of themes and genres. It’s a coming-of-age and mystery, at times both comedic and horrific. The Flynn family ties it all together. Husband and wife, Bud and Catherine, have lost their spark, and they’re navigating their own midlife crises separately. When they open their marriage, Bud unwillingly, their daughters Abigail, Louise, and Harper all cope in different ways. Abigail is known as the pretty 17-year-old girl next door with a rebellious streak. She stays out all night and falls for older, obscure men. Louise, 15, suffers from classic middle child syndrome, distressed by a lack of individuality and her sisters getting all of the attention. 12-year-old Harper is a straight-up child genius, and she knows it, spending her time teaching herself languages, lying, creating problems, and then solving them.
My review of Lost Lambs
As you’ve probably picked up on, a lot happens in this novel, most of it zany and outrageous. It tackles heavy subjects like dysfunctional family dynamics, feelings of isolation, parenthood, and the struggles of growing up as a bored, precocious girl with lightheartedness. It feels like a wink at the absurdity of life and how it’s inescapable, no matter your age.
What lured me in and kept me coming back is Cash’s writing style: It’s distinct, funny, and sure of itself. The dialogue throughout the book bounces back and forth with ease, reminding me of watching a tennis rally. It’s impossible not to devour. And the characters were just as charming as the voice.
Each character has their own vivid personality, and you get to know them individually as the chapters switch narrators. I found myself wanting to spend more time with the three girls, but there wasn’t a single character whose perspective I’d have preferred skipping. The pacing and flow of everyone’s storylines kept me hooked until the very end, and they came together like a satisfying (albeit a bit unexpected) hug. The family doesn’t really reach functionality, but such is life.
I surprisingly felt a lot of affection toward Bud, the father, empathizing with his struggles to keep his family afloat while dealing with depression. He’s helpless, in an endearing, girl-dad way. His interactions with Catherine are sparse, but whenever they are together, the anger and desperation for a past life jump off the page. It’s a picture of marriage I haven’t seen much in the media, and it’s very raw.
However, as much as I enjoyed reading about all these characters, there are a couple who I think deserved more. I didn’t love the portrayal of the mother, Catherine. Although her ennui from “giving up” a life of creativity to raise children is valid, her interiority didn’t feel fully fleshed out. The “vain, neglectful mother who drinks too much” is an overdone trope, and Cash didn’t give her enough development to combat this. Motherhood is a very complex topic, and Catherine felt like an oversimplified representation. But I still enjoyed her character overall.
So, should you read Lost Lambs?
If I had to describe this novel in one word, it would be “delightful.” I had a great time picking out the clever turns of phrase, and I cared deeply about what happened to the Flynn family, never knowing what was coming next. (I kind of wish they were real, and I could watch a show about them; they’d make captivating reality TV stars.)
I thought the book would mainly center around their faltering relationship, and it does serve as the catalyst for everything, but it’s more about everyone coming of age—the daughters as well as the parents. From Perks of Being a Wallflower to Call Me By Your Name, I’ve always had a soft spot for this kind of story, and Lost Lambs captures those classic themes of experiencing first love, feeling lost, and growth. If the idea of an entertaining, airy story that reflects Gen Z culture and family intrigues you, this offers a mental getaway while leaving you wondering, “How did we get here?” It may even inspire you to investigate a local conspiracy—or just bond with a sibling.
