Rayna struggles to piece her life back together, but hiding in plain sight from the police, the SS Crazy, and the Fallen isn't a foolproof plan—something Kade, the World's Worst Roommate, reminds her of everyday. The late nights of failing to teach Ray how to protect herself against the Fallen are getting to Kade, changing him in ways he doesn't like, and after a family emergency sends Ray back into Cam’s arms, Kade decides he's had enough.

News of Rayna's resurfacing brings both angels and the Fallen to San Francisco by the dozens, all eyes scouring the city for the girl with the gray wings. Rayna will need both Kade and Cam's help to ensure her family's safety, navigate the new dangers and enemies springing up all over the city, and manage the surprises that arise with her new set of wings.
