Dragon’s Breath by Sophie Stern

There is a legend that when a dragon finds her true mate, she comes to life.

For Natalie, that sounds like a bunch of baloney. She’s been a part of the Fablestone Clan for as long as she can remember, but she’s never met anyone who even sort of makes her feel alive. When a freak storm leaves her stranded in the mountains with no way to get home, she’s forced to seek refuge in a strange cave.

Only the cave isn’t empty, and the occupant isn’t exactly happy to see her.
Donald doesn’t want a pesky little human rummaging around in his treasure. He’s taken years to build this home for himself. It’s far away from prying eyes: just the way he likes it. When Natalie tells him her true reason for leaving Fablestone, though, Donald knows he has no choice but to return to his home.

Fablestone needs him, and he could be their only hope.
