Wolf Moon. Gabriel Hawke Novel, #14

In the remote, snowbound wilderness of Oregon's Eagle Cap Mountains, a sled dog race turns deadly. State Trooper Gabriel Hawke is teaching winter survival to Search and Rescue recruits when he's called in to find a missing musher. Arriving at the race camp, he discovers the musher isn't just a name on a list-she's someone his friend Justine cares about deeply. As Hawke searches rugged trails and icy backcountry, the case quickly shifts from a rescue to a murder investigation.
Then a second body turns up, and it's clear the killer is hiding among the racers, handlers, or volunteers. The deeper Hawke digs, the more he uncovers buried secrets and dangerous rivalries. Now, with a killer on the loose and Justine possibly in the crosshairs, Hawke must navigate blizzards, betrayal, and bloodshed-before the race ends in even more tragedy.
