It's been a good while since I've read a vampire book that I just devoured (pun but not accidental 😉)

Ruby and her twin Ripley have been training as vampire hunters until Rip is turned by the most wanted vamp, X, who strikes a deal with Ruby to rescue his BFF from her people. 

Ruby is the best. She never gave up on her sister even when at the risk of her own life. I love the soft moments we get of X. He lost a lot when he was turned and at the end, I feel he's doing things that can help redeem all the death and destruction he caused. There are surprises in the big battle at the end which I should have seen coming but they were shocking.
