The thrilling sequel to the acclaimed Beautiful Blue World follows a brave girl who must flee her country during wartime and work undercover to defeat the enemy. For fans of The War That Saved My Life and Wolf Hollow.

“A thoughtful, pellucid story . . . [that] gently probes questions of loyalty, patriotism and sacrifice.” —The Wall Street Journal on Beautiful Blue World

A war took Mathilde away from her family when she was chosen to serve her country, Sofarende, with other children working on a secret military project.

But now the other children—including her best friend, Megs—have fled to safety, and Mathilde is all alone, determined to complete her mission.

In this powerful and deeply moving sequel to the acclaimed Beautiful Blue World, Mathilde must make her way through a new stage of the war. Haunted by the bold choice she made on the night she chose her country’s future over her own well-being, she clings to the promise Megs made long ago: “Whatever happens, I’ll be with you.”
