Duplicity (The Transformed #5)
Alrekur Vidarsson had to wait three thousand years to finally fall in love. He spent two thousand years searching for her, only to die before finding her.
She found him. Unfortunately, she was engaged to another, and Alrekur would have to fight and wait for his happily ever after...except that it wasn't that easy. Nor will the happily ever after.
The entire dragon species has been awakened after more than three thousand years, and they have their sights on Alrekur's family. They'll stop at nothing to get what they want, not caring if they destroy everyone he loves in the process.
