This is another of those difficult to review books, as there were bits that I liked and bits that I didn't. I've decided to grade each part separately: 
 THE COVER: Five Stars 
 Most of the time, I pay little attention to book covers. I sometimes wonder how important they continue to be, given that my Kindle opens the book at Page One, skipping right past the cover. And there are many seriously good books with atrociously bad covers (cough, Kate Daniels series). However, once in a while, a cover will grab your attention, and so it was with this book. I absolutely adore the artwork on this book. It's utterly beautiful and the most eye-catching cover I've seen in yonks. 
 THE WORLD-BUILDING: Four Stars 
 We are introduced to the Comarre, blood servants to noble vampires. The Comarre are a special race of humans with very pure blood, and owning one is something of an elite status symbol. They are usually treated like pampered pets, yet in many ways, they are little more than slaves belonging to their vampire masters. The book doesn't delve too deeply into the morality of this (something I would like to have read), but we do learn that they aren't quite the pure, white, virginal innocents that we are initially led to believe. I've read about vampire blood slaves before, but never in such a well-developed society as is presented in this book. I really liked learning about their world and their rules, and their hidden agendas! I also loved the story behind the signum (the gold body markings). It was original and imaginative and I enjoyed everything I learned about Comarre society in general. 
 THE STORY: Three Stars 
 The first half, or maybe even two-thirds, of the book was quite slow. I found my attention wandering a little and frequently putting the book down. I did finish it in two days, but that was mostly because I was too lazy to move off the couch and my Kindle was just THERE! If I'd had better things to do, it would probably have taken me a week or more to finish. However, it does get better and the last third was very, very good with lots of action and excitement. There were a couple of excellent twists that I didn't see coming, all of which made the ending worth the slog. It's just a shame that it took so long to get there. 
 THE CHARACTERS: Two Stars 
 Although I loved the idea of the Comarre in general, I wasn't much taken with Chrysabelle specifically. I couldn't relate to her at all. She didn't infuriate or disgust me; she was just a bit too bland for that. Though I did became tired of hearing about how superlative she was, being, like, the bestest, most perfect, toughest, prettiest, signumed-up Comarre ever. I found her interactions with Mal to be quite tiresome early on. They seemed to be full of contrived tension, just for the sake of it. If this was supposed to build drama, it failed spectacularly. I liked Mal a bit better, though he wasn't a swoon-worthy vamp. Of the two, I felt more sympathy for him, but frequently, especially in the first half of the book, I found both of them quite irritating. 
 THE BADDIE: One Star 
 I loves me a good baddie! I love reading about complex, multi-layered, mysterious, amoral baddies. Often, I empathise, when I'm probably not supposed to. Let's just say that wasn't the case here. If you want to read about a one-dimensional cartoon-style evil monster, welcome aboard! Yeah, we get that Tatiana's the baddie, but did her every single thought need to be about how power-crazed she was and how little she cared for every single person around her. No-one's actually like that. Even psychopaths have some sort of warped morals. The author went way too far in ramming down our throats how evil Tatiana was, to the point where she became a ridiculous figure. And some seriously bad shit happens to her during the course of the book, but because I'd written her off as a cartoon monster, I was fairly indifferent. Which annoys me, because I don't want to be indifferent about something like that. 
 So, averaging out the scores, Blood Rights gets three stars. Though it only scraped that because of the good ending and the surprises. The first half of the book only merits about 1.5 stars, but if you can get through that, stick with it, because it does get better (eventually!)
