The new book, Time Of The Twins, is the follow-up to the sisters’s 2014 novel, Rebels: City of Indra. The new 320-page novel will continue the story of Livia and Lex, twins with vastly different upbringings in search of “the mother they thought was dead.”

Kylie briefly previewed what to expect, writing, “In our first book Rebels: City of Indra, we left Lex and Livia in a place where their future was uncertain. Now, in Time Of The Twins, you’ll learn how these sisters struggle to get to know each other and deal with their fate.”

The book will be released on November 15, so you have time to prepare for it.
