Clutch and Claw: An epic fantasy romance (Fire and Fang) by Lindsay Buroker

Queen Syla Moonmark is delighted that she’s won the game of captives, and the dragon rider Vorik—the man she loves—now stands at her side. But her troubles are far from over. A usurper has the throne, assassins are on the hunt, and Syla still has to figure out how to keep the dangerous stormer tribes from taking over the Garden Kingdom. To make matters worse, deep within a volcano, enemy dragons have gathered to perform a ritual that could not only threaten the future of the Kingdom but might destroy humanity altogether.
