If you loved 'Hellbent' for its gritty urban fantasy vibe and morally gray protagonists, you might want to check out 'The Library at Mount Char' by Scott Hawkins. It’s got that same blend of dark humor, cosmic horror, and unhinged characters who toe the line between hero and villain. The world-building is wild—think ancient gods, twisted libraries, and a group of adopted siblings with terrifying powers. It’s not a carbon copy, but it scratches that itch for something unpredictable and brutal.
Another solid pick is 'American Gods' by Neil Gaiman, especially if you enjoyed the road-trip-meets-supernatural-conflict aspect of 'Hellbent'. Shadow’s journey through a hidden America populated by forgotten deities feels like a darker, more mythic cousin to Gregg Hurwitz’s style. Plus, the prose is gorgeous, and the themes about belief and power linger long after you finish. For something more action-packed but equally irreverent, 'Sandman Slim' by Richard Kadrey is a riot—imagine a pissed-off magician escaping hell to take revenge, with plenty of sarcasm and chaos along the way.
