Hearts of Fire - Chevalier, #1

Luca Duray has been quite happy living a solitary existence for decades. But when a steel trap around his leg catches him when he's weak and hungry, his life is irrevocably changed. He knows the wolf shifter who offers him assistance is more than he appears and immediately makes plans to keep the pup close. Disowned by his pack for being gay, Tanner McBane is forced to become a lone wolf. While on a hunt, he stumbles upon an injured dragon shifter and provides aid.
It's not easy surviving on his own and when money gets tight, he finds himself face-to-face with the dragon shifter once again during an interview. Tanner isn't sure a wolf should be working for a dragon, but he accepts the job and unknowingly creates a bond to his new boss. Soon, Tanner learns Luca isn't just his boss-he's his mate. The mating of a wolf and dragon shifter is uncharted territory for both Luca and Tanner, but they are determined to make it work despite widespread prejudice, death threats, and the untraditional pack Tanner finds himself leading.
Tanner only hopes that the bond he forms with Luca will prove to be unbreakable.
