Heart pounding perfection. Blood Bound is a mind-blowing book with deception, sacrifices, and danger on every page. Set in a dark, frightening world, Rachel Vincent has created a masterpiece.Olivia Warren is a blood tracker, and happens to be one of the best. She can track you just by having even a drop of your blood. Cameron Caballero is a name tracker, also one of the best. By knowing your name he can track you anywhere across town. When Liv's old friend Anne comes to her and tells her she wants her to help her with a murder and her daughter, Liv will have no choice but to help and all because of an oath they made as kids. Forced to work with the man she loves, but cannot have, Olivia and Cam will dive into the dangerous secrets of a world neither of them chose to be a part of.Could you imagine living in a world where your blood is something of so high value that a single drop of it could get you killed? Or being Skilled and having powers? Trackers can trace someone by blood or by a name. Travelers can transport from one place to another through shadows. Binders can, in multiple ways, bind you to another person so that you are completely under their control. Jammers can hide people so that they can basically disappear. Readers can listen to you and tell right away if you are lying or telling the truth. Blinders can make a place so dark or so light you don't even know which way is up. And, that isn't even all the skills there are. How terrifying yet neat it must be to live in such a world. And, how creative of Rachel Vincent to create such a world. I'm in awe of how much I adore the uniqueness and dangerous aspects of it all.Blood Bound is rivaling my favorite book right now. It may very well become number one. I stayed up until 6am to finish it, and I do not regret it at all. My heart was pounding so much through out this story and I knew I would not be able to stop until I was finished. There were so many twists and jaw-dropping moments. It has everything I could have asked for. There is thrilling moments, romance, sacrifice, sex, guns, laughs, alcohol, suspense, arguing, 'aww' moments, and my list could probably go on for ever.I have to say the characters blow me out of the water as well. Olivia is SO incredibly strong, outspoken, unyielding, and impressive. To say Liv can kick ass would be an understatement, she is one hell of a saucy girl. Liv has and will sacrifice anything she needs to for the people she cares about. She is honestly one of my favorite female leads. Then, there is Cameron Caballero. First off... how effing hot is that name? I've always thought Cam was such a hot name for a guy, but his last name... Caballero... it just rolls off your tongue and it's sexy as hell. Cam is sexy as hell. Not only that, but he's so protective and smart. How persistent he is towards Liv and how much he truly cares about her just warms your heart... even though at one point I wanted to kick him in the shins. I truly love these two together, and I will be rooting for them for the entire series.There were other main characters as well and they were all enjoyable, and I believe all them have more story to tell and secrets to be revealed and I cannot wait to find out about them all.To live in the city created in Blood Bound you have to be potentially reckless and/or brave. And I am blown away by the darkness and the thrilling story that Rachel Vincent has created. My heart was pounding so many times through out this book, it was unbelievable to me because I normally don't get that way. Once you get a few chapters in, you are hooked and you better hang on tight because it is a hell of a ride with tons of turns. To say I loved this book would be an understatement. I adored it; I am in love with it. The next book is told from Kori's POV, but we still get to see Cam & Liv (Phew!)... needless to say I cannot wait for Shadow Bound. A zillion stars out of five!
