By a #1 New York Times best-selling writer. A grand sequel to The Counselor. The “Kincaid Cave,” hidden for over a hundred years in the Grand Canyon, may contain sacred writings and artifacts proving the truth of Travis Call’s cherished religion. And just as important, it may hold proof of a vast conspiracy committed to keeping those artifacts secret. Against the wishes of those who love him, Travis descends into the canyon to find evidence, not only of the artifacts, and not only of the conspiracy, but also of the murder of a friend. Travis Call only wants answers, but he may find more evil and opposition than he expects in his quest for an ultimate truth.
