A Dragon's Heart — Tamelia Tumlin

When Gatekeeper and Amazon tour guide Zeke Townsend finds Elena Torres on the streets of Rio during Carnaval desperately searching for her missing sister, he knows he's the only one who can help her. But fighting his growing attraction for Elena isn't easy, even if he is bound by honor to marry another air dragon.

Then Elena does the unthinkable. She crosses his portal illegally to search for her sister in the Jarithian realm. As a Gatekeeper, Zeke is required by Jarithian law to turn her over to the Elder Court for punishment.

Now, he must choose between upholding his duty as a Gatekeeper or saving Elena by making her his...mate!
