Sam MacKenzie is a fire fighter who knows no fear. There's no one waiting for him at home, no reason not to risk it all. Out of the blue, the only woman he's ever loved - the same one who ground his heart to dust ten years ago - shows up begging him for help. Dianna's sister is in big trouble somewhere in the rugged Colorado Rockies, and he's the only person Dianna knows with the skills to track her sister down.
Working together on their quest, they soon realise there's a killer on the loose and his true target isn't Dianna's sister...it's Dianna herself. Using his extreme outdoor skills, Sam needs to track down the killer, before he loses the woman he loves forever.
