Fans of "The Legend of Korra" and "Avatar: The Last Airbender" are receiving another release date delay, this time with the Avatar legacy book.

"Avatar: The Last Airbender—Legacy" is a recently announced book published by Insight Editions. The production description for this intriguing book is as follows, according to Avatar the Last Airbender Online.

"Earth. Air. Fire. Water. These are the four nations that lived in harmony until the Fire Nation attacked. For the next hundred years, war raged across the globe. It was believed that all inhabitants from the Air Nation had perished. Then, a girl and her brother discovered a twelve-year-old boy frozen in an iceberg. His name: Aang. He is the Avatar, the master of all four elements. Together Aang and his friends went on to save the world!"

"Now a man, Aang looks back on these adventurous years-from being found in the ice to fighting epic battles to negotiating peace. This is Aang’s story, his mementos, and keepsakes. 'Avatar: The Last Airbender—Legacy' is the collection that Aang passes down to his son Tenzin, who will one day be a master Airbender, too. Readers will relish Aang’s heroic tales and the posters, clippings, cards, and maps he gathered along the way!”

Despite it seemingly being a tie-in to "The Legend of Korra," it's been reported that the release date has been pushed back from October to Spring of 2015, with a specific release date to be announced next year.

Meanwhile, "The Legend of Korra" fans are anticipating a release date for Book 3, and the next likely event to make such an announcement is the San Diego Comic-Con next month.
