We find out that Shane has a really complicated past, but it makes sense as to why he's so moody sometimes. His story is tragic and really explains why he hates the vampires so much. I enjoyed the complexity of his character and seeing him struggle with his beliefs. Claire has grown up a lot by this book as well. She's a lot less timid. She's more confidant, but also more risky. 
 I liked that this book looked how the world isn't just black and white. The vampires can be really evil, but so could some of the humans. Some of the things Monica does seem more evil than the things the vampires do, like when she sets Claire up to be taken advantage of. 
 Now that I'm on the third book I see all the little things the first two have included to set things up for the plot in later books. There are a lot of little details that I'm still discovering the meaning behind, and I enjoy that.
