What to read after Endgame: Sky Key?

The Endgame trilogy continues in the sequel to the New York Times bestseller Endgame: The Calling. Endgame is here. Earth Key has been found. Two keys—and nine Players—remain. The hunt for Sky Key has begun.

Queens, New York. Aisling Kopp believes the unthinkable: that Endgame can be stopped. But before she can act on her own, she is approached by the CIA. And they have their own ideas about how Endgame should be Played.

Kingdom of Aksum, Ethiopia. Hilal ibn Isa al-Salt narrowly survived an attack that leaves him horribly disfigured. But the Aksumites have a secret that is unique to their line. A secret that could help redeem all of humanity.

London, England. Sarah Alopay has found the first key. But getting Earth Key has come at a great cost to Sarah. And the only thing that keeps the demons at bay is Playing. Playing to win.

With only two keys left to claim, the remaining Players will stop at nothing to find Sky Key—wherever it is, whatever it is—as the world begins to crumble.
