One night, young Adam hears a voice calling him. A girl on the beach asks him to help, but when Adam arrives there, he only finds a mysterious key. A storm is coming to his island, and strange things keep happening. Can the girl, the key and the storm be linked? Can Adam save his island?
This is another lovely middle-grade novel with a close-knit group of friends, on an island off the coast of France. The setting is slightly Gothic and eery, and although the prose was simpler than in Les Guerriers de Glace, I found the characters more original. I would have liked a little more character development, though, but that's because I'm not used to reading middle-grade (and I'm changing that in 2021).
