The sylvan planet Emeralla has been devoured by the Waste-Wyrm, a cosmic dragon that feasts upon worlds. When Zeeky and her allies flee Emeralla back to Earth, they are pursued by the Waste-Wyrm's servant, the Kraken. The Kraken raises an army of the dead to open the interdimensional gate that will give the cosmic predator access to Earth. Can humans and dragons put aside their ancient hatreds to unite against their common foe?

Dragongate: Angels, is the thrilling conclusion to the Dragonsgate trilogy. In this saga, dragons and humans are at war in the ruins of post-apocalyptic America. In the ruins of Oak Ridge Tennessee, a malfunctioning machine hidden in a government laboratory has ripped a hole in reality, and now dinosaurs are appearing in the surrounding wilderness. When a band of adventurers led by the famed dragon-slayer, Bitterwood, sets out to destroy the malfunctioning machine, some of them are swept away to a parallel earth where humans have never evolved. On this world, magic is real due the presence of a cosmic dragon named Emeralla. Unfortunately, cosmic dragons are the favorite meal of an even larger cosmic dragon, the planet devouring Waste-Wyrm. Now, Bitterwood must battle devils, spirits, and angels across a series of parallel worlds if he hopes to save his own reality from the interstellar predator.

This series freely blends science fiction, epic fantasy, and eldritch horror, for an adventure unlike any other. It also draws in characters from James Maxey's previous sagas, Bitterwood and Dragon Apocalypse, though the series can be read without having previously read those works.
