A companion to the New York Times bestselling Endgame series, The Complete Zero Line Chronicles is a collection of prequel novellas that follows the Zero Line, an underground group of conspiracy theorists determined to put a stop to Endgame - and save the world. Several decades before the Players of Endgame meet at the Calling, an earlier generation of Players is learning the rules. Each has been chosen as the one to save their ancient bloodline-and win Endgame.
