If someone had told me beforehand how this summer would turn out, I wouldn't have believed it. That I would meet someone during these totally ordinary, boring holidays who turns my world upside down and makes my heart explode. And that I would be pulled into a world full of secrets and superstars. A world I could never have imagined being a part of. Yeah, right, I would have said. Just chill out. But then it became the summer when everything happened.

Help, my crush is a star! Karoline with a K is fourteen and would prefer to spend the summer holidays with her best friend Emma. Instead, she has to go to her grandmother's camping site. Totally lame! While she is bored to death, Emma is having the summer of her life on Instagram and soon has better things to do than facetiming with her. But then Mathias suddenly shows up at the campsite. He’s cute, looks incredibly good, and Karoline falls for him immediately. The summer seems saved, but Mathias has a secret and has to keep going back to Oslo. When Karoline barges into a shoot with Norwegian superstar Chrissy, the secret is revealed, and the summer really kicks off!.
