Kendall Jenner and Kylie Jenner might not be satisfied with their joint clothing line, successful family reality show, Kylie’s lip product line and Kendall’s modelling career –  and so they’re heading further into the world of the written word. That’s right, the sisters are writers. They are credited writers of an actual published book and have yet another one on the way.

Kendall and her little sister Kylie are credited as the writers of an epic sci-fi tale of twin sisters living in a sort of dystopia. Despite the whispers of there being a ghost writer involved,

Rebels: City of Indra seemed to do well enough such that a sequel is in the works.

On May 23rd the brunettes took to their Twitters to announce the sequel and its title, sharing what appears to be a picture of a draft of the story. The protagonist twin sisters from Rebels: City of Indra go on yet another adventure in Time of the Twins, and are interestingly enough made to be the written likeness of real life sisters Kylie and Kendall. 

In speaking about the 2014 prequel Kylie has said that Lexi was written to mirror her and Livia to mirror Kendall. Writers Elizabeth Killmond-Roman and Katherine Killmond are also cited as authors for the upcoming young adult novel.

Interested? Lexi and Livia’s followup tale gets released November 15.
