Fire and Redemption - The Tear Stone Collectors, #1

When a dragon cries, their tears fall as precious jewels. Each tear stone is imbued withthe magic of its creator. And for special humans, the jewels can enhance the person'snatural powers or even provide the ability to take on dragon form Shunned by his kind and expelled from the dragon isle, Medraut is forced to shed his wings and take on human form to live amongst the people of the mainland. His problem? There are slayers, sworn to kill all dragons.  Brial has one chance to stop the fever ravaging her kin, but her healer powers have not yet awakened.
To have the future she desires, she must survive the fever, raiders, and most of all, Medraut's dragon ability to control minds.  Karst, son of the head slayer, was disowned and sent on an impossible quest to kill a dragon. Rather than return to his village and be subjected to the deadly justice of the Goddess, he made himself a home in the trading wagons of Clan Vreis. His newfound happiness is threatened when the caravan stops to help an injured man lying in the caravan's path.
