Divergent

These young adult books don't really have much that isn't covered in the film. I just read it to see if I should continue the series. Although the majority of the book is quite strong, the ending is daft. There really isn't a middle to speak of.
If you don't have anything else to read, I guess you can give it a try. However, there is too much better stuff out there to bother with this one.
I'll definitely watch the movies though :P
