Alien Prince's Bloodmate - Alien Warrior Brides, #8

ANDARAndar is the deposed Adesran prince and head of a small clan of royalists; he is also one of the last honorable vampires on the planet. He has mastered his blood hunger, in stark contrast to the usurper Valock. Without a throne, he and his clan try to fight against Valock's cruelty. But when Valock hears a prophecy, he begins to steal Mashek moon daughters. Andar must unseat Valock once and for all.
He doesn't expect one of the moon daughters to be his fated blood mate. Now they're on a journey to defeat Valock and restore the planet to the way that it should be. KANAKana lived in a hidden valley with her Mashek family until the day that the Rippers came and stole her from her home. Now she must fight to survive Valock's plans for her to be the mother of the first hybrid Adesran-Mashek baby, the child prophesied to bring peace to the planet at last.
