Lauren Jauregui, 18, a rising pop star in a girl group Fifth Harmony along with Dinah Jane, Ally Brooke and Normani Kordei, rich and famous in Miami meets Camila Cabello, 17, a Cuban girl that had just moved into town. ((I ain't good at summaries))

It was 2 years ago that Madison came home to something unexpected. 2 years ago she found something on her bed. A note. A note that could possible change her life forever. A note that could send her through years of sadness, misery, guilt and disorders. Plenty of them. Demi Lovato, her older sister isn't here to help her. Why? Well because she is the cause of the note. She is the person that wrote it. Will Madison find her older sister Demi and be released from all of the depression that she has been suffering from for the the past 2 years or will finding Demi do the complete opposite. But... To find out what will happen, she needs to actually find Demi first.

Camila, Lauren, Ally, Dinah, and Normani. Five girls who have become Fifth Harmony and won third place on X-Factor. After the competition, they get signed to Simon's record label, and take a long trip to England to record some songs with the one and only One Direction! But more happens on this European journey than recording hit singles. Especially after the contest.
