Holy *#&!, this is so amazing.
First off, the art is unique to say the least. As previous reviewers have mentioned, it has a raw and surreal quality that is perfect for the story. Personally, I adore this weird, crazy art, but it's definitely not everyone's cup of tea.
Second, the story and characters. The implications of poverty and its psychological impact are handled extremely well. Also, what seemed like a very cliche story about a poor student trying to make her way through life, turned out to be one of the most interesting and unique stories I've read. While the story does fall to certain cliches, like the super annoying female wanna-be-enemy of the main character, on the whole, the characters are very human, very three-dimensional, and you can connect to what they're feeling and the way their minds work. There's more to some of the characters than is seen at first - simply speaking, what may seem perfect may very well be an illusion.
I personally found this to be a thought provoking and addicting read. And I did end up crying through a lot of it, because alot of what happened was just so personal and I could relate to a lot of it. Definitely read this one no matter what.
