Bunny tells the story of Samantha Heather Mackey, who couldn't be more of an outsider in her small, highly selective MFA program at New England's Warren University. A scholarship student who prefers the company of her dark imagination to that of most people, Samantha is utterly repelled by the rest of her fiction writing cohort—a clique of unbearably twee yet menacing rich girls who call each other "Bunny." When Samantha receives an invitation to the Bunnies' fabled "Smut Salon," everything suddenly changes and she finds herself inexplicably drawn to their front door—ditching her only friend, Ava, in the process. As Samantha plunges deeper and deeper into the sinister yet saccharine world of the Bunny cult and starts to take part in their ritualistic off-campus "Workshop," the edges of reality begin to blur, and her friendships with Ava and the Bunnies are brought into deadly collision.
