One simple prank on the boys has a massive waterfall of side effects...

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?

Ella Payne is sixteen now. She's still Niall's little princess, and still Liam and Meg's little sister. She's really everyone's little sister. It really can't get any better. Meg and Louis finally got to settle down together. They think it's all over. Daddy and Mummy are gone. No more troubles. It's much farther than that. When they shoved everything behind them into the doors and locked it with a key, there was one door they forgot about. Once a new neighbor unexpectedly moves in, they've only realized they've gotten much deeper into the water, much closer to danger. Relationships will be tested, tears will be shed, and if anything, there will be blood.

For her 16th birthday, Lucy Martin received a "present" from her childhood bestfriend, Louis Tomlinson; she got to be a backup dancer for One Direction. Things started heating up with her and Harry, but after the tour, he broke things off. Shortly after the breakup, Lucy discovered she was pregnant. With Harry Styles' baby, she decided to keep it a secret, only telling Louis the truth. Now, 3 years later, Isobele stumbles into her father, totally by accident. Should Lucy let the curly haired boy into his daughter's life, or shut him out like he did to her, all those years ago?
