Damnation Robot

In an infinite universe, evil knows no limits …
When a black hole exploded, killing Blaze and Elle’s father and opening the demonic Onyx Gate, they had no idea how much their lives would change.
Now, thirty years later, Blaze is a highly trained astral Marine, and Elle is a powerful Onyx witch. Together, the siblings have formed an uneasy alliance with a misfit crew of aliens and monsters to track down demons, snare ghosts, and destroy hellish creatures bent on murder—all to discover how to close the Onyx Gate for good.
There’s just one problem. A demon-possessed robot has infiltrated their starship, the Lizzie Borden, and a vicious coven of stellar vampires have stranded them in a graveyard of ships at the edge of known space. All the while, an unimaginable evil is brewing—one they cannot possibly destroy.
