Immortal Rage. Blood Revelation, #6

The Blood Revelation Prophecy: Vampires, witches, and shifters will band together to stop the darkness from winning, until one warrior is born to save the world from Satan's wrath. After a botched summoning unleashes a dark entity and a series of missteps leads darkness right to her door, Seta must accept the help of her sire in order to keep her family safe. Eron is the only one capable of controlling the fiery vampire-witch, but that control comes with a price.
The more he uses his power to protect her, the more she resents his ability to do so, fueling a rage that has always burned deep within.  Seta trusted a man completely once, and all was stolen from her. Can Eron convince her in time that placing her trust in him is the only way to not lose all again?
