Valknut: The Binding — Marie M. Loughin

An' the black bird o' sorrow
lay his blue eye upon you
an' you fall
an' you fall
an' no one catches you
at all...

When Lennie Cook hops a freight train in a desperate search for her father, she's thrust into an underworld of hobos, gangbangers, and serial killers. But human foes are the least of Lennie's worries. On the iron road, amid the lost, the restless, and the strange, an ancient battle between gods is taking place. Lennie comes face to face with Fenrir the Wolf, whose quest for vengeance threatens to plunge the world into madness.

His first target is Lennie, who has the power to stop him--if only she can figure out how.

Aided by road-hardened Junkyard Doug and simple-souled Jungle Jim, Lennie uncovers the deadly family secret that drove her father to desert her. A secret that could derail Fenrir's plans…

Or cost Lennie her life.
