From New York Times bestselling author Amy Ewing comes the second book in the epic YA fantasy duology that SLJ called “rich and complex.”

Sera is ready to go home. Agnes and Leo have secured passage on a ship that will take them to their grandmother, the only person with the means to reach Braxos. The magical tether connecting the human planet and the City Above the Sky, Sera’s home, is anchored on Braxos. Though the journey will be treacherous, Sera is willing to risk everything to be reunited with her mothers and best friend, Leela.

Meanwhile, Sera’s beloved city is in turmoil. And Leela must channel the courage and curiosity that once made Sera an outcast to ensure Sera’s return and save their city. Leela mustn’t raise too much suspicion, not until she uncovers the High Priestess’s plans.

With the help of friends, family, and their Cerulean magic, Leela and Sera could soon go back to their normal lives. But will Leela be able to serve her City as blindly as she once did? And will Sera be able to leave behind all that she’s grown to love?
