Knives Out meets The Inheritance Games with magic in this standalone supernatural thriller by Sarah Henning: thirteen witches, a locked-room murder, and two non-magical sisters trapped in a deadly game of Clue Ruby and her sister, Wren, are normal, middle-class Colorado high school students working a summer job at the local Renaissance Fest to supplement their meager college savings. So when an eccentric old lady asks them to impersonate her long-absent grandchildren at a fancy dinner party at the jaw-dropping rate of two grand―each―for a single night… Wren insists it’s a no-brainer. Make some cash, have some fun, do a good deed. But less than an hour into the evening at the mysterious Hegemony Manor, Ruby is sure she must have lost her mind to have agreed to this.
