A Touch of Dragon Fire: The Complete Series

Dragon shifters have a horrific habit of kidnapping human children to sacrifice to their goddess. They miscalculated when they took expert thief Yara Parmstone's little brother, though. Now, Yara is out for revenge-after she finds the final key that will allow her to save him. But the three scorching hot, mysterious men who hold that key have a message for Yara-the dragon goddess has something important in store for her.
Too bad it's not as fun as a forked dragon tongue. Soon, Yara's racing against time to steal back her brother before his fate-and hers-are sealed.
