In a world where marriage is forbidden, sex is only granted to male warriors, and the outer realm is full of murderous creatures, Arianna fights to protect the life of her only living relative, her brother. Tardon, an elite warrior, is granted anything he desires by the Elders, but finds little joy in the voluptuous women presented to him. Born for the bloodlust found only in battle, complicated emotions emerge when he discovers his equal in the alluring warrior, Arianna.

Charged by the Elders with saving the castle from attack, Tardon and Arianna risk the curse when they traverse the vast outer realm to retrieve serum from the Tree of Life. If successful, the Elders have promised Tardon the right to marry and Arianna the cure for her brother's death fever. Will their love carry them through or will the discovery of a great deception be their ultimate demise?
