Gay Romance: Deep Sea Diary. Gay fantasy romance, #18

Kirk Ruiz, once a mercenary, encountered disaster during a protection assignment in the Bermuda Sea. When he miraculously survived, he awoke to find himself in the prehistoric Cretaceous era, surrounded by dinosaurs that should have long turned to stone, screeching and shrieking in disbelief. The first "welcome gift" this damned world offered him was a tail strike to the head from a Mosasaurus. The second was a towering brute of a wild man who clearly had a few screws loose.
Kirk had thought this was merely a conventional case of time travel-until he learned that the Mosasaurus and the wild man were one and the same. The savage even bore tattoo-like markings resembling coded inscriptions. The most bewildering revelation, however, was that whatever one imagined in this world became reality. Could this truly be just time travel?
