Carter Morrison didn't want to kill his friends, or himself, but he had a good reason. It was them, or the end of all life on the planet. Their sacrifice saved the world. Not that anyone knew it. Until Katherine Manners stumbled over a melting man in a computer room clutching a message of doom from another world. Follow Carter Morrison, Catherine Manners, Elandine the Queen of Hazurrium, and Jason Cole - also known as the Betrayer - as they try to understand, survive, save, and in Jason's case, break free of the fictional worlds that insulate Earth from the dangers of the Strange, where world-eating monstrosities called planetovores lurk.
