Call of the wraith
(Book)

"A Junior Library Guild selection" -- Dust jacket.

Christopher Rowe has no idea who he is. After being shipwrecked in Devonshire, he wakes up alone, his memories gone. Villagers tell him he was possessed by an unseen evil, and only became conscious after being visited by the local witch. As Christopher tries to get his bearings, he realizes his current state may be far from coincidence. Dark events have been happening in this corner of Britain--village children are disappearing without a trace. There are whispers that the malevolent ghost of the White Lady has returned to steal the children away, one by one, and consume their souls. Thankfully, friends Tom and Sally find Christopher and help him reconnect with his unique skills and talents, even as his memories elude him. But as motives and secrets are revealed, Christopher finds himself in a desperate race to reclaim his memories and discover the missing children before it's too late.
