"A new home ... a perfect family ... a deadly secret"--Cover.

Sixteen-year-old Tom Cavanagh--a survivor of past trauma who suffers from anxiety--befriends Alice, a new girl at his school and the former inhabitant of his home, hoping to rescue her from the secrets she seems to be concealing.

Tom's family have moved into their dream home, but soon he notices that something is very wrong: there are strange messages written on the wall and locks on the bedroom doors. On the outside. The previous owners have moved just across the road and they seem like the perfect family. Their daughter Amy is enigmatic but Tom is sure she's got something to hide. And he isn't going to stop until he finds the truth behind those locked doors. - adapted from back cover.
