The rift. Part one

Omtale

Avatar Aang asks his friends to help him honor Yangchen's Festival--one of the highest Air Nomad holidays, which hasn't been celebrated in over one hundred years. But cryptic visits from the spirit of Avatar Yangchen herself lead Aang to discover a jointly owned Fire Nation and Earth Kingdom refinery--operating on land sacred to the Airbenders! Is this the cause of the pollution Aang finds there, or is a more mysterious menace afoot? * The official continuation of Airbender from the original series creators! * Continues to top the sales charts! * The perfect companion to The Legend of Korra! "One of the best new pop culture mythologies to debut in the last decade."--Kotaku "A fantastic glimpse into the post-series universe."--Bleeding Cool
