Blood Entwined (Blood Enchanted, Book 2)

Two hearts. Two souls. And they have chosen.
Ellie Durand had no idea what she was getting herself into when she agreed to leave her home in Auckland with Hakan Bahar, a Vampire Prince of Mhachkay. Telling herself that she'd do anything to help her twin brother, Luc, she blindly stepped through a portal to wherever the hell he was taking her. But no sooner had she arrived in Istanbul than the infuriatingly sexy vampire disappeared. Right after her brother. But Éliane is a Durand. And Durands don't give up.
They also never show fear. Never give an inch. And always stay on guard.
Armed with a sword, two silver stakes and an attitude most would be wise to steer clear of; Ellie sets out to find both her brother and the vampire who has stolen her heart. But time is running out, her need to join to a kindred vampire is approaching, and more monsters are crawling out of the shadows, hunting Ellie.
Two hearts. Two souls. And they have chosen.
But what and who will Ellie choose and will it be enough to save her?
