Piper by Kathi S. Barton

Piper and her warrior sisters had been around for several millennia. Their time of fighting wars and conquering kingdoms was now a distant memory. Before Queen Dante passed, she’d graced her prized warriors—the falcon, hawk, eagle, phoenix, vulture, and owl—with humanity as well as immortality.
Piper wasn’t really happy with the way her job was going and how much travel that would be required of her in the near future. She liked the art that she made, but she wanted to do whatever she wanted, not fill specific orders. She wasn’t feeling the inspiration for that.

Grant had lived in Queen Dante’s kingdom since before the old king had died. He and his mother were fae and, therefore, immortal. He had done many things over his lifetime. Being fae and their unity with the earth, Grant and his mother were the healers for their community.
When Grant and his mother were invited to King Dante’s new castle for dinner, he was excited to see what the new king had done with the place. What he didn’t expect was the charge of magic he’d receive when he met Piper. It knocked them both on their asses. Neither knew what to expect from the other, nor what magic they had exchanged. Although Piper was wary, Grant couldn’t wait to find out.
