It's quite refreshing to see a male protaganist, especially one that actually feels like a male protaganist. There's a lot of little things that Blake did in this novel that I'm huge fan of. Overall, I quite enjoyed Anna Dressed in Blood. 
 At first I was concerned because Cas' character felt like an alternate universe Dean Winchester (not that there's anything wrong with Dean, he's a wonderful character, but we've already got one). So I was really glad to see him come into his own as the story progressed. The other characters were also similarly cliched at first but were able to walk out of that into characters I enjoyed interacting with (or they got dead, that happens). I was also pleased with the cursing - I found it was employed correctly and helped to make the dialogue realistic. 
 While the sentences felt a bit clunky in some parts, Blake's descriptions were lovely and definitely skin crawling. (view spoiler)[KITTY! Aside from being super creepy, I don't think Tybalt deserved such, the poor thing (hide spoiler)]. She also did an excellent job of bringing in humour in a natural way. It kind of reminded me of Buffy or Supernatural, the idea of having to keep your spirits up and how people laugh and make jokes about the things that terrify them. 
 I found the romance of the novel felt rushed; I think if the novel had have been longer that it could've been explored better and develop more naturally. Also, there were some plot hole and bits that just got dropped that could've been looked into more like (view spoiler)[why couldn't Anna kill Cas? It could not've been insta-love, since she wanted to kill him, but it never gets explained, (hide spoiler)]. Oddly enough my biggest issue with Anna was just consistency in continuity; it was difficult to follow events sometimes, it felt like days were missing and little things like whether the house was 2 or 4 storeys. Not a huge deal really. 
 I enjoyed this novel and look forward to seeing more from Blake. 
 3.5/5
