Khristen is a teenager who, her mother believes, was marked by greatness as a baby when she died for a moment and then came back to life. After Khristen's failing boarding school for gifted teens closes its doors, and she finds that her mother has disappeared, she ranges across the dead landscape and washes up at a "resort" on the shores of a mysterious, putrid lake the elderly residents there call "Big Girl." In a rotting honeycomb of rooms, these old ones plot actions to punish corporations and people they consider culpable in the destruction of the final scraps of nature's beauty.
