Roy Dawnseve cares more for philosophy than battle. But, in a society that shuns literature in favour of their ongoing war, Roy must face a difficult choice: brave the front lines or investigate the identity of their foes in the Orphic Basilica, an ancient, abandoned library. When Roy chooses to unravel the mystery, it soon becomes clear that the Orphic Basilica isn't without its own horrors. Strange voices echo down the halls, ghosts roam the bookshelves, and those who stepped foot in the library have either emerged insane or were driven to their own demise. Roy's partner in the investigation is Percival Atherton, a manipulative, enigmatic and distractingly charming scholar who has no qualms about belittling Roy. As a fierce snowstorm isolates them from civilisation, Roy and Percival must grapple with their tormented pasts, an unexpected romance, and an age-old conspiracy whose secrets are certain to wipe Northgard from history. Filled with all the yearning of a rivals-to-lovers romance, the intrigue and fear of a dark academia, and the wonder and discovery of an epic fantasy, Honour & Heresy is ultimately a story of self-discovery amidst the chaos of war and a long, cold winter.
