What you don't remember can't hurt you... Cyan has lived on the Island of Elsewhere for as long as he can remember, free from sadness, responsibility and tears. But nightmares and whispers of memories are making him question what he has had to forget to live this carefree life.

Then a new girl arrives, Jonquil, who seems determined to resist the sanctuary's treatment. When she vanishes, and Cyan is the only resident who remembers her, he realises something very dark is at play...
