This is the third book in the Bloodlines series, a spin-off series of the Vampire Academy series. 
 This is so far may favorite book of the series. This is mostly because of the Sydney and Adrian scenes, which to be honest was about 90% of the book. However, saying this, it makes it sound like its all about their epic love story, which it is not. (view spoiler)[We left the last book off with Adrian having confessed his true love to Sydney and Sydney responding with a "that can never happen again!" (hide spoiler)] So obviously I had to jump into the next book of the series right away! (view spoiler)[This novel starts off shortly after the second book ends. Ms. Terwilliger grabs Sydney out of bed to perform a spell that only she can perform. At this point we find out that Ms. Terwilliger's older sister is an evil witch that is seeking out other young witches to suck out, essentially their souls to steal their power and beauty. Throughout the whole book Sydney, with the help of Adrian and Ms. Terwilliger, is trying to stop Taylor, Ms. Terwilliger's sister. For some of the young witches they are too late, but for other they get there in time to warn them. While looking for Taylor Sydney and Adrian meet Alicia, who we find out at the end of the book was Taylor's apprentice. Key word was, because Alicia sucked Taylor's soul, after Taylor taught Alicia how to do it. A battle ensues between Sydney and Alicia and Sydney seems to have defeated her...Alicia's body has disappeared. Another key plot to this book is Sydney and her journey on discovering the truth about the alchemists. She finds out about this fellow named Marcus Finch who is the leader of this rebelled alchemist group. She goes on this journey of breaking the alchemist tattoo and by the end of the book she's a double agent of sorts, working form the inside. Unfolding the alchemist lies. And last, but not least, there is Adrian. At the beginning Adrian is pissed and hurt at Sydney because of what went down at the end of the second book. Within a few chapter he decides that he will love Sydney from afar, until Sydney realizes that she loves Adrian as well. Throughout the book, Sydney goes through so much character development with every aspect of her life. At the end, she has accepted that the alchemists are not always right and to let her heart decide some things for her instead of letting her head lead all her life choices. At the end Sydney uses Logic as well as Love to lead her life. (hide spoiler)] 
 My only real complaints about this book would be that at the beginning Richelle Mead takes up about twenty pages explaining the world that she has built, as though we hadn't read the last two books before this one. I found this a bit annoying because it was information that I already knew and I though that it was unnecessary for her to do that. There were certain places where it was boring because it was information overload. Though this was necessary for the novel, I still found it boring. 
 Overall I really loved this book and absolutely cannot wait until I start the fourth book. 5 out of 5 stars. Pick up Vampire Academy and the spin-off Bloodlines series if you haven't already. 
 HAPPY READINGS!!!!
