Feathers of Dawn (The Graveyard Trees #1) by Jess Galaxie:
 
This cozy, queer book about dragons is perfect for D&D fans who love a good combination of fluff and violence.

After fighting and killing dragons for years, Asith Evourin is finally enjoying an early retirement, using his free time to trace the location of his father, who's been missing since Asith's youth. But all that changes when a Bronze dragon lands in a field of his small village. Asith is the only dragon knight who can step up to protect Cairn from the wrath of this beast, but in doing so, Asith is kidnapped by the dragon and brought back to their hoard.

Surprised he hasn't become an instant meal, Asith interrogates the dragon, named Dradevai, to gather enough information to plan an escape. But he doesn't expect Dradevai to be such a lonely, gentle soul. Everything he knows about the dragon knights might be wrong, and befriending this dragon might prove some shocking discoveries, such as the whereabouts of his father.

Recognizing that a close relationship with a dragon might jeopardize their safety, Asith must decide how close to keep Dradevai and how badly he wants to uncover the history of the dragon knights and his homeland.
