Theory, a warrior of the Astorian Guard stationed in Rhettick, harbors a dream to escape the prying eyes of a society that wouldn't understand his true nature. As a Carrier, Theory faces the ordeal of a heat every moon, a dangerous anomaly that must be concealed at all costs, lest it paint a target on his back. Theory's life takes an unexpected turn when he's offered a mission that could secure his future: deliver a crucial package to the Elven Embassy. The promise of enough coin to fulfill his dream is tantalizing, but there's a catch: his partner is Veniro, the one Shifter Theory loathes with every fiber of his being. Why? He's cold, aloof, and worst of all...a Breeder. As Theory and Niro delve deeper into their task, they uncover truths that suggest their mission might be a facade for something much larger and more sinister than they had anticipated. The Black Curse weaves a tale of forbidden romance between two natural-born enemies, thrust together in a dance of destiny and danger. As they navigate a path riddled with deceit, hidden agendas, and an attraction that defies their nature, Theory and Niro must confront not only the enemies that lurk in the shadows but also the verities within their own hearts. In a world where being different is a perilous affair, their forbidden bond might be the key to unraveling the mysteries of their mission and the only chance to prevent the looming catastrophe that threatens to engulf Astoria. Or it just might bring them to the feet of the mad High King: Killian Innis. This book contains high heat (in some cases, quite literally). It is intended for mature audiences.
