On a world cursed to be covered in clouds, the elite eagle-riding Rift Riders rule the skies. Five years after the events of the Wingborn series, a new class is ready to join them - but this year's crop is unlike any other. The first Ihran to ever to train as a Rider; a rebellious princess in hiding; an atheist cast out of a deeply religious society; a student from the land where Riders are banned - and Rhiddyl. The Riders have never trained anyone quite like her before. But it isn't so easy to reach Aquila, the Rider's legendary home. First they must pass the selection school and face the Choice, where they will be united with their eagle companions in a bond that will last the rest of their lives. No pressure. Welcome back to the Overworld. A new adventure has begun.
