Heart of the Dragon(2005)

Gena Showalter

Grace Carlyle's world was about to change . . .

Deep in the jungle on the trail of her missing brother, Grace never expected to find a secret world populated by mythological monsters -- nor guarded by a sword-wielding being whose beauty put mortal men to shame.

Darius en Kragin belongs to a race of shape-shifting warriors sworn to guard Atlantis and kill all travelers who stray within its boundaries. Yet when Grace stumbles into his realm, he finds himself tempted to betray his centuries-old vow.

Now their forbidden love will either bring their worlds together -- or tear them both apart.
