<P> Since the conclusion of the original series in July 2008, fans of Avatar: The Last Airbender have demanded a more satisfying denouement in relation to the fates of the main characters . In late 2010, Samantha Robertson, an editor at (Dark Horse Comics) at the time, approached comic author Gene Yang, who was best known for his American Born Chinese series . After "some conversations" with her and the creators of Avatar: The Last Airbender, Michael Dante DiMartino and Bryan Konietzko, Yang was contracted to write three graphic novels to serve as a direct sequel to the original series . Yang's approach to the writing of The Promise is purported to be "purist", and he has collaborated closely with DiMartino and Konietzko . The first volume of this new series of comics was released on January 25, 2012 . </P> <P> The Promise Part 1 has received mostly positive reviews, with Convention Scene praising Yang's portrayal of the characters . Convention Scene also praised Gurihiru Studio's artwork, stating that it did justice to the series . The Seattle Post-Intelligencer called the graphic novel an "enjoyable read even if you are not well versed in the story's universe ." </P> <P> However, The Promise Part 2 has received mixed reviews and The Promise Part 3 has received mixed to outright negative reviews . This is attributed to the comics' treatment of characters who backtrack in their development from the original series and make foolish mistakes or outright out - of - character actions . </P>
