Humanity faces extinction. Ten-kiloton monsters are rising from the depths of the Pacific, levelling entire cities in frenzies of destruction. Earth's heroes have been decimated. The survivors put their hope in one last, desperate plan: find Hyperion, Earth's most powerful hero, and ask him to return from exile to save them.

What they don't know is that Hyperion is dead.

The Griffin spent ten years fighting wars across the sector as a weapon of mass destruction for the il'Drach Empire. His victories made his name a curse on a dozen worlds and a nightmare on scores more. He retired to the peaceful station Wistful and discovered that leaving his name behind didn't clear his sins, his debts, or his conscience.

Earth's peril may give him a chance for redemption, if he can only find a way to stop the monsters without turning into one. Without becoming The Griffin again.
