Avalon was thriving. The cold sleep colonists from Earth had settled on a verdant, livable world. The fast and cunning predators humans named “grendels” were under control, and the mainland outposts well established. Avalon’s new mainland hydroelectric power station was nearly complete, and when on-line would compensate for the nuclear power systems lost in the Grendel Wars. Humans would have power, and with power came the ability to make all the necessities for life. They would survive. They would not survive as a spacefaring people.

A new generation is growing up on the island paradise of Camelot, ignorant of the Great Grendel Wars fought when their parents and grandparents first arrived on Earth. Setting out to explore the mainland, this group of young rebels feels ready to fight any grendels that get in their way. On Avalon, however, there are monsters that dwarf the ones their parents fought, and as the group will soon learn, monsters also dwell in the human heart. Avalon does not give up her secrets easily, and some of those mysteries are wicked as sin and blacker than the grave.

While J. Robert Oppenheimer and his Manhattan Project team struggle to develop the A-bomb, Edward Teller wants something even more devastating: a weapon based on nuclear fusion - the mechanism that powers the sun. But Teller’s research leads to a terrifying discovery: by the year 2030, the sun will eject its outermost layer, destroying the entire inner solar system - including Earth. After the war ends, Oppenheimer’s physicists combine forces with Albert Einstein, computing pioneer John von Neumann, and rocket designer Wernher von Braun.
