Obsidian - The Dragon Kings, #1

Aspen doesn't know how to behave in front of the shifter dragon king.... And the consequences are deadly. But, Aspen, never one to fear much of anything, tells him to get lost. If she knew who he was, she might act differently. But to her, Sid is just a reminder of a past she'd rather forget. Sid won't leave Aspen alone, because she's the one girl that might be able to help save him and the rest of the dragons.
He hadn't planned on falling love.
