A worthy sequel, with the same whip-smart plot, effortless world building, and delicious warmth. I raced through it... A must-read for all fans of adventure - children or not. * Kiran Millwood Hargrave, author of The Girl of Ink and Stars *
Moonlocket is a spellbinding sequel, a roller coaster journey full of catastrophe, buried secrets, breathtaking courage and intrigue. * Lancashire Post *
Deliciously dark and irresistibly gripping, Moonlocket proves to be another extraordinary story that you won't want to forget. * Jo Clarke, BookloverJo *
Me and my older son really enjoy reading it. It is great reading, full of mysterious adventures and it took 3 evenings for my 9 years old child to finish! I have to admit that is even better than Cogheart. We are looking forward for the third one... * Malgorzata, Waterstones bookseller *
Normally, the sequel to a great book is generally never quite as good. But Moonlocket was as good, maybe even better! I loved the adventure, the thrill and at times the terror. You never knew what was going to happen next. It was full of surprises. * The Tween Book Blog *


Author Biography

Peter grew up in South London in a rambling Victorian house with three cats, two dogs, one sister, an antique-dealer dad and an artist mum. He is a BAFTA-winning animator, as well as a writer and film-maker. Like Lily and Robert, he loves adventures and reading penny dreadfuls, but wishes dearly that he had a mechanical fox called Malkin. Shadowsea is his fourth novel.
