In a hidden world beneath everyday human life, the Protector Guild wages a secret war against demons to keep humanity safe. Max Bentley, a naive and ferociously capable new hunter, arrives at the Guild's Pacific Northwest academy alongside her protective brother, ignorant of her own mysterious origins. The most elite team of hunters — grumpy, antagonistic, and impossible to ignore — immediately marks her as a liability.

Max Bentley is the series' secret weapon — naively earnest and devastatingly capable in equal measure, her social awkwardness generates both comedy and genuine tension. She grows organically, never losing the authenticity that makes readers root for her from page one. Her bond with her brother Rowan is one of the emotional cores of the series.

Across eight books, Max grows from a socially oblivious rookie into a formidable force within the Guild, untangling the dark secrets of her own past while navigating the complex 'found-family' dynamics of her team. Romance evolves in a slow burn through multiple partners, reflecting the series' open-relationship resolution. The Gothic PNW academy setting gives way to ever-larger supernatural stakes.
