The search for a ruthless hit man

turns into a deadly alpine chase…

Undercover to track the assassin who killed his partner, FBI special agent Alex Driscoll accidentally pulls his partner’s widow, Violet Sharp, and her search-and-rescue K-9, Teddy, into the case. Now, with Violet’s life on the line, the only way Alex can protect her is to make her—and her enormous dog—his new cover. But can they stay alive long enough to bring the hit man to justice?
