Cassie "Sassy" Williams has a normal life down in Salem, Massachusetts. She has a small group of friends, an older sister, a mother, and a father. She's a freshmen in college and a Beatlemaniac. She plays guitar and piano. She has a best friend. A Directioner best friend, even though Sass hates One Direction. Louis has the dream life. He's a multi-millionaire, international superstar. His birthday is the day before Christmas Eve, for God's sake! But for a reason unknown to anyone but him and his mother, every year when winter comes around, Lou loses his bubbly, happy-go-lucky, i-don't-give-a-fuck-and-neither-should-you attitude. These two very different people have some seemingly unrelated secrets. Zayn... Zayn just changed. Perrie left him for an old ex, and he shut down and became the steryotypical famous boy, expecting the world to love him when he doesn't help the world do shit. But there's still enough of the old him left to know that there's something off about that "Sassy" girl Lou's so obsessed with. Something very off. When three worlds collide, what happens?
