When Jackie Ellis attends school in Texas she soon finds out who the school bad boy is, but what happens when she starts to get curious about what happens to the bad boy outside of school when he's not breaking girls hearts or knocking someone out? Will he let her into his life or will he turn his back to her when he needs the most help? Or will Logan leave her in the dust when she needs him most?

It was only 50 days, she would tell herself. It can't be that bad right? Well it was. Sadie Burns was your typical bad girl. Leather jacket, combat boots, and different colored hair every 2 weeks. She hated pop music and hated boy bands even more. So, how did she get stuck making a bet with Kendall Schmidt? His side was that he could make her fall for him and like their music. Her side was that she wouldn't fall for him, and if so, they would get out of her life. She hates him but he adores her. Sadie is sure she is going to win, Kendall's not so sure. Could he break her bad girl reputation? Could Sadie get this boy band blondie out of her life? The biggest question is, after 50 days with Big Time Rush, who's going to win?

Dedicated to @louanne_xo (@rawritslou) :) After Logan Henderson breaks up with Lourdes Marie because he cheated on her with a "bad girl" aka, Samantha Droke, she falls for Carlos Pena, her bestfriend since she was born. After escaping death so many times, will she forgive and forget everything that Logan has done to her or will it be a fairytale ending where she ends up with her bestfriend?
