Rebels: City of Indra

Rebels: City of Indra is a 2014 science fiction/dystopian novel by Kendall Jenner, Kylie Jenner, and ghostwriter Maya Sloan.

Background

Kylie spoke about the novel, saying "The fans seem to love it. That’s why we did it, ' names are Lexi and Livia. I think we wanted to make Lex more like me and Livia more like Kendall, and they kind of evolved into their own characters."
Main characters

Lex and Livia Cosmo — are the twin daughters of Arnaud Cosmos and Delphia. Lex is a hard-scrabbled, bullheaded, tough-talking orphan while Livia is an indignant, bullheaded debutant orphan. They both have a small neon-green symbol on their eyes.
Marius — is a semi-ineffectual pseudo-intellectual who runs about citing manners for Livia.
The Governess — is Livia's beauty-obsessed debutante coach who gets her wrinkles removed yearly at the Rejuvenation Island Clinic

Reception

Publishers Weekly gave a positive review: "Details about the two worlds the girls inhabit are creative, though the plot that emerges after they meet is rather predictable. Even so, abundant action — including a hair-pulling fight, a high-speed chase on flying machines, and an attack by hideous beings known as 'mutations' — provides momentum. Unresolved conflicts set the scene for the next installment."
