Avatar: The Last Airbender: Imbalance, Part One by Faith Erin Hicks is the continuation of the comics featuring Aang after the end of the television series. It's the first story in the series by Hicks, taking over from Gene Luen Yang.
Aang, Katara, Sokka, and Toph visit the Earthen Fire Industries factory, first featured in the "The Rift" sequence. The once frontier town and factory has boomed and now there are multiple factories. There is also a new kind of rift between the benders and the non-benders. It's a precursor to the political unrest that will face Republic City in Korra's time.
It's been five years since I read and reviewed "The Rift" and my faulty memory made diving into Hick's story harder than it should have been. Beyond that the story's a little rough around the edges but this is her first time writing these characters beyond a short in an anthology. That said, it was good enough for me to purchase Part Two which came out in April. I have it on hand and will be reading it soon.
