Vicious was definitely different from everything i've read before! The story was really intriguing, dark and pretty creepy I really enjoyed it. 
 What made the story all of the above was naturally the characters. The way that Victor and Eli thought gave me chills and I didn't really approve of what they were doing. They are so twisted! I ended up rooting for Victor because I feel the book let's you know a bit more about him (view spoiler)[and he didn't run around killing people... (hide spoiler)]. I also really liked his companions, Sydney and Mitch and of course, Dol. All of the characters in this book were complex and well-developed and had interesting backstories! 
 I really liked the way this story was told, jumping between charcters and the past and the present. That really showed how everything happened, how everyone's thoughts developed and how it all wove together. That worked really well with this kind of intense story.
