Return of the Griffin

● "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." ― quoted from this book's Amazon product page as of 2023-11-20.
