In this book so far, I have found out the main character's name is Caitlin. Very early in the book Caitlin's sister Cass has runaway. After Cass runs away her parents are so upset and scared that they even forgot Caitlin's birthday. There's one thing you must understand about Cass. Cass is a star athlete and a star student. She sent an application to five different schools and got into four of them. Overall she chose Yale, and when she didn't show up for first semester they realized something wasn't right. Not long after her disappearance Cass makes a phone call home, saying that she is okay, and she is happy where she is. She never included where she was or she was with just that she was happy. The day after the call Caitlin's best friend Rina persuaded her to try out for the cheer leading squad. Caitlin and Rina both made the squad.
