Driven By Destiny by Lindsay Buroker

Arwen Forester is on a quest to remove her dark-elven tattoo and get her mother’s evil people out of her life forever. The last thing she wants is for them to magically manipulate her into betraying Azerdash Starblade, the half-dragon refugee she has feelings for.

But when an old elven comrade visits Azerdash, sharing the location of one of the invaluable galaxy blades that were made for his kind, Arwen must set aside her own quest to help him. This may be a chance for him to once again become the leader he was meant to be.
But there are people—and dragons—who will kill to keep the powerful sword from returning to Azerdash’s hands. And they would have no problem slaying Arwen in the process. Is his quest worth dying for?
