Lady Fair

Pure humans can't use magic. Yet Tabitha can not only use it, but has sworn to kill with it, and her easiest target is the renegade dragon, Ru. Far from terrifying him, he's fascinated by her abilities. But when the shop owned by Ru's friends, Nicholas and Annie, is attacked, she's forced to not only get to safety with the very creature she must kill, but to acknowledge that what should be hatred is actually desire. Worse yet, he might feel the same way.

A unique twist on dragon shapeshifters, Lady Fair is the second book in the series, The Will of the Unknown.
