In Nazi-occupied Holland, seventeen-year-old Noa snatches a baby from a train bound for the concentration camps, fleeing with him into the snowy wilderness surrounding the train tracks. Passing through the woods is a German circus, led by the heroic Herr Neuhoff. They agree to take in Noa and the baby, on one condition: to earn her keep, Noa must master the flying trapeze – under the tutorage of mysterious aerialist, Astrid.Soaring high above the crowds, Noa and Astrid must learn to trust one another…or plummet. But with the threat of war closing in, loyalty can become the most dangerous trait of all.
