Naomi is the biggest pop star on the planet at the age of fifteen. She’s broken America, she’s big in Japan, she’s on top of the world… but she’s also tired of the constant touring, bored of having Westfield shopping centre closed for her to wander alone at midnight, miserable at not having any friends.

Ruby is Naomi’s biggest fan. She knows the words to every song, she can replicate every dance move, she dreams of being Naomi’s BFF. When the girls have an unexpected encounter and swap bodies, Ruby is launched into the limelight.

Will she adore her new A-list life, or will she end up as lonely as Naomi? And will Naomi discover she can be a huge celebrity AND a normal girl after all?
