The Dragon’s Slave by Lacey St. Sin

Book 1 of the Amber Aerie Dragon Lords Series (Amber Aerie Lords)

Woman. Virgin. Sex slave. Three words that describe Gayriel on the day she is to be sold into service. But words could be deceiving, and so could she. Because there was nothing she wouldn't do to walk the world free, never to suffer a touch she did not desire. She expected it would be difficult, and she expected it would be dangerous—the very act of escape would forfeit her life if she was caught. What she didn't expect was him.

Dynarys Firestriker, general of the Amber Aerie guard. Dragon Lord. Half Breed. His very blood is a legacy he must fight to overcome, and slipping a female spy into his enemy's midst is the easiest way to prove himself. But the slave he chooses for the task is anything but easy. Worse, she tempts his beast, a complication he definitely doesn't need. Not with a traitor in his Aerie and one in his delegation. Can he rein in control long enough to salvage his mission? Does he even want to? They say a dragon's mate is the pinnacle of what it means to love...what of a dragon's slave?
