I didn't particularly care for this book; it was just okay. The story was interesting enough, but the writing of the characters, especially the protagonist Tris, didn't really manage to engage me. The characters seemed rather one dimensional and unbelievable. Also, I didn't much like that it is written in the present tense, which is awkward. There was no compelling reason for using this tense to tell the story, so it just felt like a device to make it seem more interesting. For me, it didn't work. I'll probably still see the movie to see how the book was interpreted to film. I may even try reading the second book, as I've often experienced in reading sequels that the authors' writing improves.
