Winner of the CILIP Carnegie Medal 2018. Every summer Quill and his friends are put ashore on a remote sea stac to hunt birds. But this summer, no one arrives to take them home. Surely nothing but the end of the world can explain why they've been abandoned - cold, starving and clinging to life, in the grip of a murderous ocean. How will they survive? Brilliant, beautiful... as unpredictable as the sea itself". PHILIP REEVE, author of The Mortal Engines.
