The Search should be coming out in September, around when the third and final portion of The Promise comes out.
The Promise?
Yeah. It takes place about a year after the end of the 100 years war. Zuko took the throne and promised he would return all of the fire nation colonies to the Earth kingdom - but in the colonies, the Fire nation colonials and Earth kingdom citizens are so well mixed, that removing them is just as upsetting as letting them stay. Zuko goes back on his promise because he thinks it's for the best, and the earth king is pissed. That's pretty much the story thus far.
