"Eden McKinley knows she can't count on much in this world, but she can depend on Bonnie, her solid, steady, straight-A best friend. So it's a bit of a surprise when Bonnie runs away with the boyfriend Eden knows nothing about five days before the start of their final exams. Especially when the police arrive on her doorstep and Eden finds out that Bonnie's boyfriend is actually their music teacher, Mr. Cohn. Sworn to secrecy and bound by loyalty, only Eden knows Bonnie's location, and that's the way it has to stay. There's no way she's betraying her best friend. Not even when she's faced with police questioning, suspicious parents, and her own growing doubts. As the days pass and things begin to unravel, Eden is forced to question everything she thought she knew about the world, her best friend, and herself."-- Publisher's description.
