This was a little too similar to Chris Bohjalian's The Night Strangers....
A family buys a rambling old house that they're going to restore, moving to a small town after trouble in their past. In House of Echoes the family has two sons, The Night Strangers it was two girls. Something is off about the town, the people. And then the real strangeness happens.
Not a bad book at all, actually I probably enjoyed it a little more than The Night Strangers. Maybe if I read them two years apart instead of two weeks!
