The World of Divergent: The Path to Allegiant (Divergent, #2.5)

The World of Divergent: The Path to Allegiant - Veronica Roth This was a great refresher as I'm getting ready to read Allegiant, the final book in this trilogy. In this little bonus book, author Veronica Roth talks more about the World of Divergent, including more descriptions of each of the factions. It's a fun little time waster, and while not a necessary read, a good way to brush up on your details of this special world.
