The much-anticipated final installment in Olivie Blake's trilogy that began with the New York Times bestselling phenomenon, The Atlas Six.

Only the extraordinary are chosen. Only the cunning survive.

An explosive return to the library leaves the six Alexandrians lethally vulnerable to the terms of their recruitment, driving the fractured alliances to opposing strategies. While those who remain with the archives wrestle with the ethics of their astronomical abilities, an unlikely partnership seeks to influence politics on a global stage.

While each member of the erstwhile cohort does what it takes to secure their place on the board, the outside world mobilizes to destroy them, and the Caretaker himself, Atlas Blakely, may yet succeed with a plan foreseen to have world-ending stakes. It's a race to survive as the six Society recruits are faced with the question of what they're willing to betray for limitless power--and who will be destroyed along the way.
