Dragon’s Heart by Eden Ashe

The dragon-shifter king will do anything to keep his mate alive…even if it means war.
“We’re dragons. We don’t do the mushy friend thing.” – Daniel
After millennia as king of the dragon-shifters, Daniel Ashborne wants a little peace and quiet, especially from the beautiful Hollywood starlet who haunts his memories. His escape tactics end abruptly when he is called to the ER to save the one woman he wants to forget, but who now bears his mark.
Shelby Kincade’s life and movie career were nearly destroyed when Daniel vanished a year ago. Now he’s back, claiming they have been accidentally mated. Getting over him once was hard enough, but she must choose either the life of her dreams or the man she can’t live without.
With peace finally on the horizon between the dragon-shifters and the Hunters, an assassination attempt on the dragon king and his mate shatters everything. Tensions rebuild as Daniel and his loyal team of shifters try to discover who put out the hit. Enemy and ally lines are crossed, but in the end–after the battle ash has settled–no one could have foreseen who has plotted for their own gain.
