In a world where dragons hatch from stars, Peregrine Kent would give anything to see the sky.
It's an impossible dream. The Barrier surrounding his planet makes sure of that. Everyone else might feel safe, but the flat white sky just makes Per feels trapped. His OCD has been getting worse each day; if he could only be out among the stars, though, he would finally feel free.
His dream seems impossible...until the day a real live star dragon tears a hole in the sky, setting off a worldwide panic. With the help of a homemade submarine and its surly-and distractingly handsome-captain, Per sets off on a quest to escape the confines of his world and his own anxiety. But what he discovers instead is a devastating truth that will change everything he thought he knew about dragons, his planet, and himself.
