"Big-city detective Bentley Jamison is a long way from home in the Beartooth wilderness when one of local rancher Maddie Conner's ranch hands goes missing. Towering mountains and a small, tight community are as unfamiliar to Jamison as herding sheep, but he's never shied away from a challenge. As the new deputy sheriff, he's sworn to protect every inch of this rough terrain--starting with unraveling a mystery that has left Maddie a wide-open target. Maddie's as beautiful--and untamable--as the land around them. Like Jamison, she won't back down from danger. But desire that flares hotter than their tempers only raises the stakes when a fierce storm traps them in the high mountains. Caught in a killer's sights, Jamison and Maddie must trust one another, because now survival ... and love ... are all that matter"--Publisher.
