The Neutronium Alchemist

The war of the Possessed has proved that souls are real, eternally suffering in the Beyond, desperate to escape. Across the galaxy, trauma-shocked humans ask, "Why fight an enemy you will become? Why live, die, exist at all?"
As the war rages on, Adamists and Edenists become allies; a 20th-century crime lord masterminds a conquering army; a seductress lays siege to a sentient habitat as she lures children to their doom; and a satanist's path of horror heads inexorably toward Earth.
But amid the devastation, some of the Possessed battle their own kind to save lives. For not all of the damned are evil...and heroes, too, are returning from the Beyond.
