Bloodwitch Luz Oscuria 
Novae Terrae, Volume 3 [EPUB ebook] 

The Vampire Hunter of the Order of the Eternals is gone, along with all those with whom he tried to protect the Novae Terrae when they faced an army of Vampires led by Eleonore and Aleksis who assaulted the citadel in which Tomasz, Mylena and the Eternals were lying in wait. But all is not lost. There is still hope in Sarah. Born from the union of a Hunter and a Witch, she is an exceptional being who still promises many surprises for the Vampires. The two clans will this time be surrounded by new allies of their own choice, and the outcome of this story is more than uncertain.
