Rex Graves is the protagonist of C.S. Challinor’s series, a dark fantasy adventure following a disillusioned ex-military operative who now works as a private investigator in a perpetually rain-soaked, morally ambiguous city. The books blend elements of noir, grimdark fantasy, and investigative thriller, characterized by a bleak tone and Graves’ cynical, world-weary perspective as he confronts supernatural threats and human corruption.
