Another day, another new Kardashian-Jenner venture.
Not content with being a reality TV star and high fashion model, Kendall Jenner will soon be adding author to her CV.
The young adult novel, called Rebels: City of Indra, is set in a dystopian future.
It tells the story of 'two super-powered girls, Lex and Livia, who embark on a journey together, not realising their biggest danger might be each other.'
Kendall said of the project: 'Kylie and I loved the creative challenge and are thrilled to have been given the opportunity to share this story.'
This isnt the first time the sisters have worked together.
18-year-old Kendall and 16-year-old Kylie have also designed their own clothing range for Californian line Pacsun, and recently revealed they have been working on a new shoe and handbag collaboration with Steve Maddon.
The sisters have been working with author Maya Sloane on the book and are keeping it in the family with Karen Hunter, the same publisher as Mum Kris 2011 memoir.
The stars' debut novel will be released on 3 June.
