A short novel "Katara: A Private Life of the Bloodbender" is one of Avatar: The Last Airbender fan fictions of psychological lyric story. Ten chapters narrate about the emotions, feelings and expressions of Katara in a third book of the series, about how much her character changed during one year voyaging with Avatar and about her inner shock which she suffered from after conflict with Hama the bloodbender, during the dangerous invasion and Zuko's coming into the team. The novel points especially at Katara's hardship during these seasons, caused not only by many disheartening challenges she have to face, but also by depression connected with a new full moon and the bloodbender's psychosis. The story provides Katara's point of view, unlike most of the fanfictions (and also the TV series) which present mainly Zuko's point of view and he is shown as a misunderstood hero and don't really care about his hostile and traitor's role in most of the original storyline. Austere plot of the novel proves sadly that not all the sacrifices are assessed positively, neither between friends everything is always fair and impartial, and it also shows how quickly the insidious psychical disease can completely shatter even the most beautiful friendship and the strongest relationships. The novel contains many of the original story, mainly the episodes "The Western Air Temple", "The Desert", "The Southern Raiders" and "The Puppetmaster".
