For Sheridan St. John, things just haven't been the same since September. It's early autumn when wall-flower Sheridan and her perfect best friend, Cyndi, move to the city to begin their lives as young adults. On their own for the first time - and away from the harsh criticisms of Sheridan's mom - the girls are enjoying their new independence. But after a wild night partying, Sheridan's grip on reality starts to weaken. When a gruesome tragedy then strikes her family, she's convinced it's all been an epic nightmare... one from which she must awaken if she is to survive.
