Nominated for the CILIP Carnegie Medal 2022What you don't remember can't hurt you... Cyan has lived at the Elsewhere Sanctuary for as long as he can remember, freed by Dr Haven from dark memories of his past life. But when Cyan finds a mysterious warning carved into the bones of a whale skeleton, he starts to wonder what he had to forget to be so happy. New resident, Jonquil, begins to resist the sanctuary's treatment, preferring to hold on to her memories - even the bad ones. So when Dr Haven resorts to harsher measures, Cyan embarks on a secret mission to discover the truth about the sanctuary...and himself. "Marvellously visual and gripping" - A. M. Howell
