Katara and her brother free a boy and a flying bison from a block of ice, a boy who is an airbender destined to be the Avatar, unfortunately Prince Zuko has been turned out of the palace until the airbender is dead. Contains all the addictive elements of fantasy; an engaging adventure, mythology foretelling destiny, magic powers. Images are very expressive and carry action sequences as well as functioning as part of the plot. Text reading level is available to all readers. I would put it in an elementary or middle school collection, although it does have shiny pages so I might put a copy through rigorous abuse tests before purchasing the entire series. ( )
