Following a year of therapy, 15-year-0ld Megan vowed never to speak to another ghost. When she moved from Boston to Phoenix, her new friend Izzy asked her to help investigate the 1975 murder of David, her irritating house ghost. Megan internally struggles to keep her promise, only to have it backfire. Determined to get rid of David for good, they found themselves in the middle of illegal and terrifying situations.

Rita Toma's new Young Adult mystery, the latest in a series featuring a trio of young crime solvers, takes hero Megan's ability to see and talk with ghosts a step farther: the ghosts of the victims assist in the investigation. Laced with humor, the story is fast-paced, and the characters are eminently relatable. Beyond the basic mystery is another layer that is perhaps equally important: the plight of teens who fall prey to grown-ups and peers alike. The lessons learned are worth the price alone, but the twists and turns will keep you turning the pages, wondering where the clues lead.
