Mercury off Course — Steve Rzasa

Hold your breath... Mercury Hale is hunting Syndax, the evil soldiers bent on summoning astral fiends, when he finds himself reliving the trauma  of his battle against the Hedron of Orbits. Suddenly his bravado, his boldness, and his abilities are called into question. Meanwhile, Homeland Security dogs his steps as he and Loredana trace a mysterious mutated creature across the country, from the American heartland to the Florida coast. Forces converge in the depths of the Atlantic, where Mercury races Syndax and Homeland to the source of the trouble, only to face his greatest enemy yet... His fear.
