The youngest sisters of the reality TV show "Keeping Up With the Kardashians" have added to their already impressive resumes by writing a young adult novel set in a dystopian future. The thrilling story entitled "Rebels: City of Indra" is about two sisters, Livia and Lex, who embark upon an adventure. According to E! News, which got hold of a publisher's note, the story develops when the duo finds that the biggest danger along their journey might be each other. According to Karen Hunter Publishing, the novel appears to be the first of a series, suggesting that this might not be the only book that the sisters will be writing.

Kendall Jenner, 18, told E! News that she and her 16-year-old sister Kylie love the creative challenge. Kylie expressed her excitement as well, saying that she can't wait to share with readers the world and the characters they had created. For their story, which is set 200 years in the future, they collaborated with writer Maya Sloan. Kendall said that they wanted to do something different -- something that they really love. As to what inspired them in coming up with "Rebels: City of Indra," Kendall said that they decided to come up with something that they would like to see in a movie.

The book series will add to the sisters' already lucrative empire. Kendall Jenner is already gaining popularity as a runway model, and she was recently seen with Anna Wintour of Vogue. The two sisters are brand ambassadors for Seventeen Magazine as well. Also worth mentioning is the clothing line that they launched together with PacSun. With all the success Kendall and Kylie are achieving and will be able to achieve in the future, celebrity followers expect them to become more loved than their older half-sisters Kim, Kourtney and Khloe.
