Sixteen-year-old Tom’s mother has had a string of bad luck with men, but now she is married to Jay, who is exactly who he says he is – a nice guy – and they have recently moved into a brand new house. Not everything is perfect. Jay’s daughter, Nia, is also living with them. She’s a year older and clearly hates Tom. And although the house is Tom’s mom’s dream come true, Tom soon makes an odd discovery. It looks like someone had installed locks on the outside of two of the bedroom doors. Weird, right?

At school, Tom is tagged to show new girl, Amy, around and although Tom is slightly awkward and not all that good with the ladies, he and Amy sort of hit it off. Then Tom discovers that Amy used to live in his old house. As bits and pieces of Amy’s life are revealed Tom starts to think that things just don’t add up. But the more he pushes Amy, the stranger things get. When Tom meets Amy’s family, June and Chris and Amy’s younger brother, Will, and makes some new discoveries in his new home, well – it all makes for page-turning fun.

Tom is a clever and likeable character who suffers from OCD.

I’m worse when I’m worried. On good days, I can touch everything once and sleep like a baby. On the worst days, I check everything twenty or thirty times and only make it halfway up the stairs before doing it all again. I know it’s silly, I know it’s irrational. But it’s part of me, and it’s not going anywhere.

It is perhaps partly his OCD that makes Tom so dogged when it comes to figuring out the truth. It might also be, in part, because of the horrors his mother faced prior to meeting Jay. What if Amy is in trouble? Tom can’t imagine not helping her even if it means getting himself into some scrapes.

Of course, it all comes together perhaps a tad too easily in the end, but I had a good time reading and I think teens who like mysteries will really enjoy this one.
