Forge of the Titans

When Derek Secrest was suddenly pulled out of Naval flight officer school to take part in a top secret government project involving telepathy - because tests showed that he had a strong latent talent for psi powers - he thought things couldn't get weirder. He was wrong.
Soon he was contacted by a mysterious woman who could open portals at will through spacetime. Her powers seemed godlike - and they were. Millennia ago, extra-dimensional beings with great powers had come to earth and taken on human form, remembered in legends as gods and goddesses - and titans, the ancient enemies of the gods. The godlike beings had driven off the titans, but now the old enemy is returning, with a new plan to use humans with psionic abilities to rule the Earth, and not be driven from it this time. And the titans always did have a fondness for human sacrifice.
Unless Derek and a handful of other telepaths can join forces with the ancient gods to defeat the titans, the world will be plunged into a new dark age of terror and death. Even so, judging from mythology, how much can you really trust a god ...?
