"How long have I been asleep?" Sophie wondered aloud, searching for the last memory she'd had.
It took only a few seconds for her to realize that she didn't even know who she was.

Sophie is an amnesiac. The doctors say that her memories will come back soon, but her worries are far from confined to that of her memories. Apparently, before losing her memories, Sophie agreed to pick whether she loved Keefe or Fitz by the end of summer... and now summer's nearly over. To make matters worse, no one will tell Sophie what happened to cause her amnesia, only referring to it as the "accident."
Something's going on...but will Sophie figure it out in time?
