“Riley expertly blends the moodiness of dark academia with the poignant anxieties of modern adolescence to create a punchy, engaging, and relatable story for today’s teens. Readers will root for Violet as she struggles to find herself in this world of cutthroat drama students and lofty professors. Finally, dark academia drama for all the anxious theatre nerds.” —Matteo L. Cerilli, author of Lockjaw “I was completely captivated by the eerie, intriguing universe of The Dark Cove Theatre Society—every page offered new clues that kept me hooked.” —Ashley Leggat, author of Life With Derek “The perfect read for every theatre kid at heart.” —Tatiana Schlote-Bonne, author of Such Lovely Skin “Stylish and candid, full of sharp observations about a young artist’s growing pains.” —Curtis Campbell, Dragging Mason County “Set in a lush, eerie world, The Dark Cove Theatre Society is an expertly told story that explores the nature of privilege and elitism in the arts. I fell in love with Violet, who at times seems to be simultaneously amused and intimidated by her surroundings, which feels highly relatable. If you love dark academia and spooky settings full of sapphics, this book is for you.” —E. Latimer, author of Witches of Ash and Ruin “A thrilling mix of ambition, mystery, and secrets. Sierra Riley delivers a story that is impossible to put down.” —Alexander Elliot from Hulu’s The Hardy Boys “[T]his debut with gothic touches centers on diverse, well-developed teens who challenge their school’s narrow norms . . .
