A darkly comic and unflinching feminist campus novel for the age of prescription pills, impossible beauty standards, and weaponized friendships. Fans of Mona Awad’s Bunny and Ottessa Moshfegh’s My Year of Rest and Relaxation rejoice—your newest “weird girl” antiheroes are finally here.
Intrigued? Well read on to discover the synopsis and an excerpt from Heather Colley’s The Gilded Butterfly Effect, which releases on October 21st 2025.
When introverted loner Penny transfers to a midwest university in search of the all-American college experience, she finds herself under the intoxicating influence of Stella, a glamorous, damaged sorority girl with a razor-sharp wit and a bottle full of secrets. As their unlikely friendship deepens into obsession, both young women spiral into a hall of mirrors—haunted by frat-house cruelties, prescription drug dependencies, and the brutal expectations of modern femininity.
Narrated in alternating voices, The Gilded Butterfly Effect exposes the glossy absurdities and grim realities of contemporary campus life, exploring themes of body dysmorphia, mental health, sexual assault, and peer manipulation with both ferocity and humor. This acerbic, atmospheric debut asks: how much of ourselves do we lose when trying to belong?
Colley isn’t afraid to put campus life under a microscope, examining complex topics ranging from sexual assault to prescription drug abuse to body dysmorphia with an unwavering steady hand. The Gilded Butterfly Effect is a delightfully twisted (and timely) read that promises to deliver loveably imperfect female protagonists, humor, and a whole lot of dysfunction.

Stella
I don’t really get weak at the knees. I’m not much of a romantic. Quite honestly, I haven’t got the time. Romantic types make me feel strange, as if I’m playing the part in a movie for which I’ve been entirely miscast. Romantics are all well and good until they use up my time for fun, and glory. There is only so much weekend, and after I got to Michigan, I stopped wasting it on romantics. I wasted a great deal of time on boys. But there was nothing romantic about it.
So that’s how it was on that night, and how it had been for many nights before. It was Sterling’s birthday party. He was a sophomore like us, but he was twenty-three or twenty-four, so we perceived him as archaic, washed-up, a bit creepy. Someone perched at the perimeters, hunting and drooling. And always, of course, watching. We had to be so beautiful because they—the boys—were always watching. Unzipping our skin, and looting whatever they found underneath.
It was an outdoor party, stacks of beer cans, taller than the tallest brother, and a bar with no bartender, you served yourself, and there was only one type of liquor. Clear, burning liquor that only rolls in Middle America, the type of thing that hurts on its way down, and makes me cry late at night. Music played. It was the kind of music that you knew, even if you didn’t. The air was warm with the receding summer, and Michigan seemed like a dream to us then—it always did, at the beginning of the academic year, when everybody was so pretty, and plumped up from long summers spent being overfed, and over-tanned by yoga moms and finance dads. At the edge of the yard, fraternity pledges stopped God Damn Independents from breaking in, laughed in their faces. They said, you’ll have to rush, then. And when girls were turned away, they looked up to us. Hated us deeply; and we loved that, how that felt.
It was easy to express that love through our fake, crackling laughter.
Kappa Alpha—us—and Sigma Rho—them.
There were wooden risers, the pledges built them every August and destroyed them every May. They lined the backyard, and blocked off the nearby shrubbery, where we went to undress, and admire one another naked, or to empty our bodies of excess toxic waste, because there was a certain unbeauty about alcohol poisoning that called for the quiet, and rapid disposal of it by manual force. These risers were the hierarchy in architecture. Right then, we must’ve been eight or nine feet up. From up there you saw the tops of other girls’ heads, the Betas, and the Gamma Phis, and even some God Damn Independents who’d snuck in. We saw these girls below, and knew that if we wanted to, we could toss a drink onto their dull hair, and watch it run cold under their tank tops, and into the fibers of their jeans, and nobody would say a word, apart from us, and our words would only be in laughter. Hysterical, tons of it, and I was always the one that spoke English first, and I’d say something like, “Isn’t this amazing?”
We didn’t throw any booze that night. It was too soon in the new semester to wreck the house’s image. That year was meant to be our attempt at re-affirming our prestige and decorum, an effort trailblazed by Kathy Van Tassel since she’d been elected Chapter President at the end of the last academic year.
Van Tassel was composed at this party, I saw no drugs. She was the cocaine type, and from my elevated vantage I saw that she was wired like a caged songbird, beautiful but sweaty. She never used in company.
And we all know it’s a problem when you start using alone like that. Back in August I was only a coke user socially. It was still a group effort back then. Things changed, of course; things always change in the fall.
Never mind President Van Tassel. Sigma Rho was a top fraternity, and rising every year, so this was the coupling that both chapters needed. There were constant male grips, Sigma Rho hands, pulling me back to the very top of the risers, where we pretended to have panoramic views, and loitered in heaven.
Always a boy’s hand lingering for too long, a hand perched where he assumed my butt crack started underneath my jeans, an accidental—yeah, okay—brush against my tit as I teetered up on the risers.
After a while of dancing, it got to be only pretending, for the sake of something to do. And that’s when it’s time to move on.
Millie, who was my drug-dealer firstly and my friend recreationally, had also picked up on the evident death of the party.
Yet still she said, “One more song, and one second,” and I nodded all right, the bars wouldn’t be open for a while anyway. Millie hopped down to sea level and left me amongst a dwindling group of Kappa Alphas who all looked variants of Millie, who looked a variant of me.
On the ground, Millie embarked toward a pong table with that particular focus that can come only from strong speed. She snorted something off the table, and turned around to a good-looking Sigma Rho, thanked him, and laughed. It couldn’t have been coke, not yet, since it just wasn’t an August drug. We reserved it for depressed Michigan winters, when sunlight was no longer even minimally on call. It might’ve been caffeine concentrate, I thought, which was a silly trend then, or, given the character of its user, it might’ve been something that one of her many psychiatrists had prescribed, pills which she’d crushed and broken down for easy snorting.
Who could’ve known? Who could’ve asked?
