The first review for Unleashing Colter's Hell and in. Tommy Hough with Treehuggers International writes:
"Centered around an Indiana Jones-style central character named Grayson Cole, the novel details a national security risk to the United States, with the story largely occurring at Yellowstone National Park. Sean makes great use of Yellowstone locales, an understanding of the National Park Service and the professionals who work for it, and the volcanic origins and threats posed by the Yellowstone caldera as focal points of the story."
The novel is scheduled for release in December. Stayed tuned.
