3.75 stars. 
 For a book found in the YA section, this certainly had a lot of disembowelment in it! I just mean in the first few chapters (not even getting into the rest of the book because that would just be a gore fest) are: oozing/exploding eyeballs, ripped off limbs braided together in a macabre daisy chain, and a kid gets ripped in half - VERTICALLY! I think the only reason this is in the YA section is because the main characters in it are in high school and there's no sexy times besides kissing. They could have easily been college age kids and then this would have been put in the adult section where I think it should probably go, mainly because of the graphic non-stop gore. Mind you, I'm not saying "graphic non-stop gore" like its a bad thing. Its a ghost/voodoo/horror story...gore is a given. 
 What stopped my from giving this a 4 or 5 star rating, and I know this will sound silly, I thought some aspects were just unbelievable. I'm not even talking about the ghost or witches or magic stuff. I was able to buy into all that, no problem. I'm talking about the reality issues. Cas is a ghost hunter. Besides his natural psychic-like abilities and on the job training, he really doesn't have a lot of other valuable skills if he were to actually do this profession in reality. I mean, he doesn't have real muscle bulk or even any martial arts training for Pete's sake! Why would you even pick a fight with a ghost if you don't know how to fight and you aren't particularly strong?! I'm amazed he's still alive and that his body doesn't look like ground beef from taking repeated beatings by this point. 
 Besides that though, I really enjoyed Cas as a protagonist. I felt like he sounded like a a real person. I always love a hero with some sass and I loved his sardonic, snarky attitude. That's what really sold the story for me. The fact that the characters 
 acknowledge 
 that they are in a ridiculous and scary situation. I'm not sure if that makes sense or not. I mean that they still have a sense of humor about the whole thing. Its not just super serious and everyone talks about duty and responsibility. They acknowledge that as well but they also realize that its ridiculous. Like they're fighting ghosts! That's pretty unusual! 
 As for supporting characters, I really liked Thomas and Carmel (even though "Carmel" is a really stupid name.) I enjoyed that they weren't just decorations in the Cas show. They were real people and they helped in their own ways. I also appreciated that Carmel wasn't a damsel in distress. She freaks out at points, understandably so, but she has some real mettle and doesn't just hide while the men-folk save the day. She's a force to be reckoned with considering she's the prom queen and helps hunt ghosts in her spare time. I also liked that Thomas wasn't all self doubting in his witch abilities. He also has that same mettle. They are great team members. 
 Anna's story was so tragic. I could see why Cas would be so interested in her. I really like their weird romance. (Its definitely weird considering she's a ghost and all.) I just wish I got more of their romance. I felt like it was maybe a bit threadbare in some places. I wanted to really see the relationship grow more. (view spoiler)[ Maybe she will some how come back in the next book. I mean she got sucked into hell or whatever to save Cas in the end of this story... so it may be a long road back. Considering there even is a next book, I think there will be a reunion and I'm really excited for it. (hide spoiler)] Hopefully I will get more in Girl of Nightmares.
