When Alfie Wheatcroft and his father find an injured girl alone on one of Scilly's uninhabited islands, they have no idea where she's come from or who she is. Able to speak only one word, 'Lucy', the girl is a mystery to everyone - even herself.

While the Wheatcrofts love her as one of their own, their fellow islanders are filled with wartime suspicion. As hostility mounts and hope dwindles, the key to Lucy's lost memories may lie just beyond the shoreline . . .
