When bright and bookish Oscar Lowe follows the haunting sound of an organ into the chapel of Kings College, Cambridge, one day, his whole world changes. He meets a beautiful and seductive medical student, Iris Bellwether, and her charismatic and troubled brother Eden. Oscar is seduced by their life of scholarship and privilege, but when Eden convinces Iris and her close-knit group of friends to participate in a series of disturbing experiments, Oscar fears he has entered into something from which he cannot escape. Reminiscent of Donna Tartt’s , is a gripping exploration of the line between genius and madness that will hold readers spellbound until its breathtaking conclusion.
