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?

I was just another fan to him. I didn't think by sending that one little tweet to Niall Horan, 1/5 of the famous boy band One Direction, my life would change forever. I was nothing special. Just like any other 17 year old girl. Hands touch, eyes meet and apparently, he saw something special in me.

Amberlynn Grace has been best friends with Niall Horan since she was 5 years old. When she was 15, Niall left to go audition for X-factor, and she was left behind in West Meath, only able to talk to Niall on the computer. And then, her world turns upside down. Her parents announce they are moving to America. Even farther away from Niall. Her parents tell her once she turns 18, and graduates high school she can move anywhere she wants. At first, She's upset about leaving, and tries to refuse to go. But then Niall promises her that he'll be there to get her on her graduation day. Fast forward a few years, and Niall has arrived to get her. She moves to London with Niall and the rest of the boys. The more time she spends with him, and he spends with her, the clearer something becomes to the both of them. Just without the other knowing it. It could tear them apart, or it could make them closer than ever.

Hailey Pierce has never understood the appeal of One Direction. On the other hand, her best friend Kiara is obsessed with them, especially one boy in particular. But what happens when Kiara makes her go to the final One Direction concert of their tour? What happens when Hailey happens to catch the eyes of two of the famous band members? Well one thing is for sure, The Girl With The Red Lipstick is in for a lot of trouble.
