Los Angeles, 2031. In the first spring after the collapse of the United States, peacekeeping troops have withdrawn and the city’s curfew has finally been lifted. Ari Waker and her roommate make their way across Silverlake to a party, where an already strange night takes an impossible turn: a bewildered doppelganger appears in the crowd, and the party’s host, Kareem, vanishes into thin air.

As Ari searches for answers, Exit Party expands across fractured timelines and shadow worlds, traveling from a future America splintered by civil war to the seaside cliffs of Greece, a domed Paris, and a colony on the moon. Emily St. John Mandel blends literary and speculative fiction in a story about doubles, surveillance, safety, and resilience in the face of extraordinary change.
