One day in his hotel room, Niall gets a package of twenty one letters. Twenty one letters about a girl who poured her heart out to Niall, a girl who is dying inside and is trying to fix herself again. As Niall begins to read, and the letters begin to run out, he finds himself knowing and loving this girl, all the while knowing that one day, he's going to have to stop reading. Because she stopped writing.

Megan Payne is Liam Payne's younger sister. Yes, the Liam Payne of One Direction. Sounds pretty cool, right? Not exactly. She's never even met her brother. He doesn't even know she exists. Her life without her brother was hard. Maybe if Liam didn't audition for the X Factor and left her alone, her step father wouldn't have abused her. Finally, she's had enough runs away with her little sister, Ella. The plan is to find Liam. She'd be living with her brother and the band. No one would ever hurt again...Right? Will everything go the way she planned, or will her past come crashing back down on her?

I tapped my pen onto my desk with anticipation. Why did I deserve to meet One Direction? I stared at my lifeless paper. The question kept skipping through my mind like a broken record player. Why did I, Cher Marie Lovett, deserve to meet One Direction? Lots of ideas swirled my mind, but one caught my attention. Without thinking twice, I scribbled onto the paper, “So I can lick Liam Payne's abs.” I know what you're thinking. That's probably the dumbest reason ever. But, hey, it was 100 percent truthful and its not like they're gonna read it anyways. Pretty pleased with my idea from God, I skipped over to Mrs. Richards’ desk and slammed down my masterpiece. “I'm finished,” I smirked with a mouthful of victory. Little did I know that a simple, ‘I'm finished’ would be my biggest regret yet.

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?
