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.

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) story that promises to deliver loveably imperfect female protagonists, humor, and a whole lot of dysfunction.
