A beautiful yet tough woman working in a beautiful yet tough setting, Brannon Callahan is a search and rescue helicopter pilot for the Great Smoky Mountains National Park. Strong faith and a decorated history of service have kept her one step ahead of on-the-job dangers, but there's no precedent for what's about to happen. After a blizzard takes down a small plane carrying U.S. Marshal Roark Holland (already haunted by a recent tragedy), Brannon must save him in more ways than one and safeguard the donor heart he's transporting to a government witness on the edge of death. Otherwise the largest child trafficking ring in history - with shocking links from Thailand to Tennessee - will slip further away into darkness along the Appalachian Trail.
