Deadly Little Lesson (a Touch novel) by Laurie Stolarz

Camelia's senior year should be a time of joy and discovery. So far, the only things she's discovered are a family secret, and another person in need of her help. As she heads to Rhode Island for a summer art program she begins her investigation into the disappearance of a local girl. She must learn to accept her gift if she wants to solve this mystery in time. On top of all that Camelia is dating Adam, but she misses Ben terribly, and has started wondering if things could work out for them.

I LOVED this book! I really like where she has taken these characters. I think this might be the last book, though I'm not positive. If so, it is a great ending.
