I am not sure how to review this book. It was too Epic to even allow a thread of a spoiler to ruin the experience for readers. 
 This is the first book I have read by Veronica Roth. Divergent is the best of the best. The world building is unique and innovated. The character building is excellent, you slowly learn the characters and feel their experiences, and the slow building of relationships between the characters. The characters are genuine and real as well as their responses and actions. The dialog is realistic and even in the dark world they live in, relatable. The story flow was perfect, allowing just enough information to keep you enthralled and never any information dumpage. 
 I was enthralled with this book from page one. Roth's imagination is a thrilling place to dwell. I read this book in two sittings, if it hadn't been for the fact that I have the flu I doubt I would have been able to put it down. But, alas, my NyQuil kicked in. 
 The world in which the factions live is completely original and inventive. I can't wait to immerse myself in the next installment of this series and find out what is in store for Tris and the rest of the defectors. 
 Divergent is a perfect mix of anything you are looking for in a book or series; action, adventure, sacrifice, despair, love, and most importantly, HOPE. 
 I don't know if this series will have a happy ending after the grief that was felt in this book, but I don't care. The journey was fantastic. Most books follow a certain path and it becomes predictable. Allowing your world to break away from that pattern of "happily ever after" to "I can't believe the author did that to her characters" makes a book or series go from good to legendary.
