Dragon's Rise (Shadow of the Dragon #3)

Book 3 in the Shadow of the Dragon series.

As a child, Prince Bren of Xicanth saw the devastation created when a dragon is rejected by its mate...and vowed he would never unleash that kind of horror and suffering on a woman. The promise is simple to maintain until Tynan, the dragon who shares his existence, chooses a mate and demands to claim her as only a dragon can. Bren's own needs make it almost impossible to deny his dragon the taste of her flesh that the beast so desires. But even as Bren unwillingly succumbs to the lure of the dragon's mate, he realizes something isn't right. A dragon can have only one mate...yet Tynan has claimed two...no, three different women.
