The Memory Wood / Sam Lloyd.

Elijah has lived in the Memory Wood for as long as he can remember. It’s the only home he’s ever known. Elissa has only just arrived. And she’ll do everything she can to escape. When Elijah stumbles across thirteen-year-old Elissa, in the woods where her abductor is hiding her, he refuses to alert the police. Because in his twelve years, Elijah has never had a proper friend. And he doesn’t want Elissa to leave.Not only that, Elijah knows how this can end. After all, Elissa isn’t the first girl he’s found inside the Memory Wood. As her abductor’s behaviour grows more erratic, Elissa realises that outwitting strange, lonely Elijah is her only hope of survival. Their cat-and-mouse game of deception and betrayal will determine both their fates, and whether either of them will ever leave the Memory Wood . . .
