When she locks eyes with a blonde boy in the airport, she doesn't know that that moment will change her life forever. Much to her suprise she meets someone who makes her feel special. She has never felt like the way he makes her feel. She meets someone who will change her life forever, and he was the last person she ever thought she would be in love with, Niall Horan. At first she hated One Direction, but that summer changed that for her. She met the love of her life and a group of friends that would last a life time.

Katty and her best friend Natasha get to know the boys of One Direction and experience some wild things with them. The problem is love, because love is not always simple.

She doesn't remember anything. Their first date, their first kiss, the first time he bought her flowers, their first fight. She doesn't even know who he is. She's forgotten something horrible, something no one wants to remind her of. So what exactly happens when everything disappears?
