Dare Me — Megan Abbott

Beth and me wedged tight, jeaned legs pressed against each other. The sound of our own breathing. Before we all stopped believing a tornado, or anything, could touch us, ever. Addy Hanlon and Beth Cassidy are tough, inseparable, invincible. No pair more charismatic or sophisticated. No pair more dangerous. But with the fall term, their new coach arrives and things begin to change. She has plans for the cheer squad: all sleek poise and cool command, the girls are soon entirely in her thrall. Faster, harder, higher, thinner, the stakes raised, their world contracting, they compete to risk -- everything. She, meantime, has been crossing a line of her own. From the brilliant author of The End of Everything, Dare Me is a searing novel about the allure of adulthood and the dark heart of adolescence: the fierce bonds between girls, their bitter rivalries, and their power to transform one another.
