Buried secrets

"Nicky Roth should be happy--he's finally proven that his best friend, Aaron, and Aaron's younger sister, Mya, are missing. Better yet, the police are actually doing something: they've plastered the town with missing posters, and have organized weekend search parties for the kids. But Nicky can't seem to pry his eyes from the house across the street, especially after he sees a frantic SOS coming from Aaron's room in the Peterson house. After what happened in the winter, and the warnings they got from their parents, Nicky's friends insist they can't help him investigate his neighbour anymore. If Nicky wants to find out what's going on in the Peterson house, he's going to have to do it alone"--Provided by publisher.
