The Atlas Trilogy

The initiates arrive at the Society's London headquarters under the guidance of the Caretaker, Atlas Blakely, and his assistant, Dalton Ellery. As they dive into reality-bending research, they realize "elimination" literally means sacrifice; the archives require a death to open. Before the group can collectively murder the widely disliked Callum, Libby's supposedly ordinary ex-boyfriend, Ezra Fowler, disrupts the timeline. Ezra is revealed to be a hyper-powerful time traveler and Atlas’s former partner. To protect Libby from Atlas's apocalyptic master plan, Ezra kidnaps Libby and strands her in the past, faking her death. The remaining five bind themselves to each other and the Society with a magical oath to find her.
