Edge of Dreams — Diana Pharaoh Francis

The road to hell is paved with good intentions.
And a pound of flesh.

Magical tracking expert Riley Hollis is on a mission to save five teenagers lost inside a mountain. But nothing is what it seems, and soon Riley finds herself bruised, bloodied, and embroiled in a battle to bring down a sadistic criminal dealing in human souls and the darkest of magics.

Her only hope may be to swallow her pride and ask for help from her not-quite-ex-boyfriend and his notorious brother-Tyet criminal boss, Gregg Touray. Even that may not be enough to protect her. Something has gone very wrong in the trace dimension and in Riley's head.

If she doesn't figure out how to handle the past, the present, the trace, and the bad guys, the road to hell is going to look like a great alternative.
