Beautiful Blue World is a thrilling and moving story of children who become the key to winning a war. Sofarende is at war. For twelve-year-old Mathilde, it means food shortages, feuding neighbors, and bombings. Even so, as long as she and her best friend, Megs, are together, they'll be all right. But the army is recruiting children, and paying families well for their service. If Megs takes the test, Mathilde knows she will pass. Megs hopes the army is the way to save her family. Mathilde fears it might separate them forever.

This touching and suspenseful novel is a brilliant reimagining of war, where even kindness can be a weapon, and children have the power to see what adults cannot.
