Actual rating: 3.5(This review was originally posted at My Library in the Making.)I read and loved the first book in Nikki Jefford's Spellbound series, Entangled, so when I found out about this new book of hers, I immediately grabbed the chance to review it. Sadly, Transfusion didn't quite amaze.Aurora Sky's life wasn't going all too well: her only friend was leaving her for the in-crowd, her dad often went MIA on her and her mom, and to top it all off, she even got in a fatal car crash. But thanks to her rare blood type (AB negative), Aurora was chosen by a secret government agency to be revived, in exchange of her working for them as a vampire hunter.In the first few chapters before Aurora's second life, she was spunky and sarcastic, two characteristics that almost always make me love a character. The same was true with Aurora, so I was beyond excited for the vampire hunter part of the plot to kick in. But instead, she went downhill when she learned of it. She felt trapped by the service required of her when she hadn't even chosen it, so she decided to live a careless life. She irritated me by making quite a few stupid decisions, I must admit.But the story started picking up when Fane, the hot goth who turned out to be a real gentleman, came swooping into Aurora's new hopeless life. He was sweet and, at the same time, he knew how to sweep Aurora off her feet. But he wasn't an open book, keeping a lot of things to himself. Honestly, I can't imagine this being a surprise for everyone so I'll just get it out: he's a vampire. His diet wasn't like Edward Cullen or Stefan Salvatore's, but he drank fresh blood just enough to quench his thirst and had never killed anyone, so he's still one of the good vamps.Fortunately, Aurora—and everything about this book—got better when her hunter training started, and even more so when she started taking on missions. As expected, she was daunted by the thought of killing even if they were evil vampires, but she was good at it, nonetheless. Although the characters fell flat for the most part, the climax didn't feel climactic at all, and the twist in the end somehow confused me, I still enjoyed this book. The right word to describe it would be addictive, because I read this for hours on end. The "science" behind this take on bloodsuckers was truly unique and interesting, and Jefford's clear and simple writing has me looking forward to the sequel.MY FAVORITE PARTS were Aurora and Fane's happy couple moments.
