Omaha, Nebraska.
Sarah Alopay stands at her graduation ceremony—class valedictorian, star athlete, a full life on the horizon. But she carries a secret.
When a meteor strikes her school, killing dozens, wounding hundreds, Sarah survives. Her secret saves her.

She is the Cahokian Player.

Endgame has begun.

Juliaca, Peru.
At the same moment, thousands of miles away, another meteor strikes. Jago Tlaloc walks among the wreckage. The streets teem with violence and looting. But he is safe. He has a secret too. And his secret makes him brave. Strong. Certain.

He is the Olmec Player.

He's ready.

Ready for Endgame.

Across the globe, twelve meteors slam into Earth. Cities burn. People are scared. They whisper: Is this the end of the world?

But Sarah and Jago and the ten other Players know the answer. The meteors carry a message. The Players have been summoned to The Calling. And now they must fight one another in order to survive. All but one will fail. But that one will save the world.

This is Endgame.
