The Sage Wind Blows Cold (The Mac Crow Thrillers) (Volume 1)

WILDERNESS THRILLER.  Chanticleer Dante Rossetti Awards 2014 - Official Finalist.
Bagging a killer should have been the end of it, but it was only the beginning. Young tracker Mackenzie Crow, working at his uncle's bounty hunting business, is ambivalent when an old flame pleads for help. His intuition tells him to scram and not look back, but Mac's conscience won't allow him to say 'no' to finding a lost child in the woods. Not sure where he stands with Kailee, Mac soon finds out: she is married to his old rival and has kept this from him in order to solicit his expertise. 
Once in the woods with the Search and Rescue team, Crow comes into his element and within a short time has found the child's trail. He also finds something completely unexpected: a strange set of tracks following the girl. It's clearly the day for unwanted surprises. 
Deep in the woods, desperately following the trail, he comes upon an SAR volunteer face down in the forest with an arrow in his back.  Little does Mac know, this is only the beginning of his problems.  Before this is through, he will be hunted by a psychopath and a cadre of mercenaries, all wanting to remove this nature's son from the land of the living.
