Saving the Dragon by Eden Ashe

The one male she isn’t supposed to want is the only one she can’t live without.
With her brother missing, everything in Lily Cage’s life has turned upside down. Born a Hunter, the last thing she needs is an attraction to Dallas, the scariest dragon in existence. The one known as the Destroyer.

With peace between the Hunters and Dragons hanging by a thread, one wrong move from either of them could catapult them all back into the war that has raged for centuries. But with nowhere to turn when everything she loves goes up in flames, Dallas proves nothing will stop him from protecting her. Even if it means going through their own allies.

As the friction escalates, they have a choice—stand and fight, or lose everything they never realized they wanted.
