“Something wicked this way comes.” Maria Lyon and Lily Boiten are their school’s ultimate power couple—even if no one knows it but them. Only one thing stands between them and their perfect future: campus superstar Delilah Dufrey. Golden child Delilah is a legend at the exclusive Acheron Academy, and the presumptive winner of the distinguished Cawdor Kingsley Prize. She runs the school, and if she chose, she could blow up Maria and Lily’s whole world with a pointed look, or a carefully placed word. But what Delilah doesn’t know is that Lily and Maria are willing to do anything—absolutely anything—to make their dreams come true. And the first step is unseating Delilah for the Kingsley Prize. The full scholarship, awarded to Maria, will lock in her attendance at Stanford―and four more years in a shared dorm room with Lily. Maria and Lily will stop at nothing to ensure their victory—including harnessing the dark power long rumored to be present on the former plantation that houses their school. But when feuds turn to fatalities, and madness begins to blur the distinction between what’s real and what is imagined, the girls must decide where they draw the line.
