Heart of the Dragon (Gena Showalter's Atlantis Series #1) »

Gena Showalter sold her first book at the age of 27 and now, four years later, is the New York Times and USA Today bestselling author of thirteen books, with eleven more on the way in a thrilling blend of genres: breathtaking paranormal and contemporary romances, cutting edge young adult novels, and stunning urban fantasy. 

Searching for her missing brother, Grace Carlyle never dreamed she would discover a secret world populated by mythological monsters--or find herself facing a sword-wielding being whose looks put mortal men to shame.

But there he was, Darius en Kragin, one of a race of shape-shifting warriors bound to guard the gates of Atlantis, and kill all travelers who strayed within its borders.

Now Grace's life was in his hands, and Darius had to choose between his centuries-old vow and the woman who had slipped beneath his defenses and stolen the heart of Atlantis's fiercest dragon.
