A Touch of Frost — Terry Maggert

Gideon Frost is the last survivor of Ravenwood, an orphanage scheduled for destruction at the hands of a vicious politician. Over the past century, hundreds of children have vanished, lost forever to witches who use their souls as fuel for life everlasting. On the run and alone, he'll find help in an unlikely place, when the missing children reach out to him from the land of the dead, asking him for the one thing he can deliver. Justice. But Gideon won't fight alone. Samira Alexander is a sorceress who can bridge the worlds between life and death, and she'll stand beside him as they fight against the killers who want far more than just Gideon's silence. They want his power. They want his soul. But Gideon won't give up either without a fight, and the witches of Ravenwood are about to learn a painful lesson.
