(Book)

"The governor of Wyoming gives Joe the thankless assignment of taking a tech baron on a hunting trip. Unbeknownst to them, as they trek further into the wilderness, a hunter is hot on their heels. Joe must rely on his wits and his knowledge of the outdoors to protect himself and his charge. Meanwhile, when Joe's closest friend Nate Romanowski and his own daughter Sheridan learn of the threat to his life, they follow him into the woods to rescue him, and all three come together for one final showdown."
