An ancient god of war out for vengeance, a lonely bartender, and an angry fire demon all walk into a bar. Sounds like the start of a joke, right? Well, that's almost correct.

What Color of Darkness imagines a world where ancient gods and monsters feud over thousands of years to decide the fate of humanity. Humans have a mighty champion in the war god Rathraq, who fights to make sure humankind can flourish in safety—but he's betrayed and imprisoned for thousands of years. Now Rathraq's soul has been released and forced to inhabit a scarecrow, but this won't stop his quest for revenge. Aided by the bartender Bobby, who's just trying to get by in life, Rathraq hunts for the monster queen who stole his body, clashes with an outsized fire demon, and confronts a world starkly different than the one he remembers.

A darkly funny, often violent epic that crafts a rich backstory and mythology that immediately draws the reader in, the Rumble series is a treat that should not be missed. Recommended for ages fifteen and up.
