2031. America is at war with itself, but for the first time in weeks there is some hope: the Republic of California has been declared, the curfew in Los Angeles is lifted, and everyone in the city is going to a party.

Ari, newly released from prison, arrives with her friend Gloria just as a fragile new era begins. But there are people at the party who shouldn’t be there. Something is very wrong…

Years later, living a different life in Paris, Ari remains haunted by that night. Whatever happened at the party fractured her sense of reality – and may hold the key to a very different world.
