Hunger is what you get when you mix anorexia and the 4 Horsemen mythology. I try not to read books with such subject matter because it can be rather depressing but I've heard rave reviews about this series so I thought I'd give it a try. 
 I did like our heroine, Lisa and I thought that the treatment of anorexia was done pretty well in here. Readers get to see what kind of a life Lisa has and how it's damaging to her body. I did find it a little iffy that she was given this role in order to "learn a lesson". I didn't think too much of it until after reading the sequel and felt that there was a similar theme going on. But on the bright side, the books focused on the growth of the characters and how their experiences as one of the Horsemen influences their real lives. 
 The length of the novel also made it hard for me to be truly invested in the story and Lisa. I couldn't really be involved in her story; I felt very much like an outsider looking in as opposed to being part of the story myself. 
 I did like having the other three Horsemen (Death, War, and Pestilence) making appearances as well -- and how they each gave Lisa some advice. Death, in particular, was charming with his sense of humor. Not a bad story, definitely worth giving a try.
