Stormwalker (Stormwalker Series, Book 1)

Book One of the award-winning Stormwalker series.
Half-Navajo Janet Begay possesses extraordinary power that is tied to the storms that waft across the desert.
The only person who can control her when she's caught in the storm's evocative power is Mick, a dark-haired, blue-eyed biker Janet can't seem to touch with her powers. He can wield fire and not get burned, and Janet's never sure where he goes when they're not together.
Together she and Mick investigate mysterious disappearances, which Janet fears are tied to her mother's people, the mythical gods from beneath the earth. They are helped along the way by Coyote and Crow, but these shapeshifting gods have their own agendas.
