The Jason Croft Trilogy

Collection of books, running in five parts for All-Story Weekly, written by J.U. Giesy. Occult researcher Jason Croft projects himself to world outside Sirius (the Dog Star), where he takes over the body of another and works to save his love and stop an iron-age war using "modern" technology. In the Mouthpiece of Zitu, Croft returns to find his enemies regrouping, and moves to defeat them with more technological toys. The final volume has Jason returning, one last time to this strange world, where he moves to save his wife and Son from the forces of evil.
