In Book-2 four years have passed since Azula was captured and Republic City began construction. Republic City is now built and so is Air Temple Island. Book-2 will feature, Team Avatar, challenged with ruling the United Nation- all the different bending groups now combined living in the same area- will lead to neighbourhood, "social class" issues and normal government problems- crime,work etc.
It will also feature Azula's journey to regain her bending. She will embark on a rip to a place only Avatar's have been too, in search of what was lost. Secrets will be revealed... remember:
"There are secrets you want to keep in and secrets you dare not let out, but if two can keep a secret, that means one of them is dead"
