Ten year old Olivia, or Livy, lives in Massachusetts but travels to visit her grandmother in Australia. Unfortunately she cannot remember anything about the time she visited when she was five. Something keeps tugging at the corners of her memory and when she opens the closet of the room she will be staying in, there is Bob, green, wearing a suit covered in feathers as a disguise. Is he a zombie? Is he an alien? Bob has been waiting five long years for Livy to return and help him remember what he is and where he came from so he can go home. But where could that be and how will they ever find out?
