Raintree: Haunted (Unabridged)

Their name is Raintree. It's more than a last name, more than a notation on a family tree. It's a mark of destiny. Each family member has a special gift, an otherworldly talent.
Gideon Raintree, a homicide detective, can harness electricity and talk to ghosts. He will need to wield gifts he's kept hidden to solve his newest case, which involves a relentless serial killer unleashed by the dark Ansara wizards. But first he must deal with his reaction to Hope Malory, his alluring new partner. He'd never planned on love in the midst of battle. With evil lurking at every turn, Gideon and Hope are in a race against time to save their love, their family, and their newly conceived child.
