But Jay quickly discovers a major mistake: No one seems to know a thing about his brother. Ray's not on the attendance lists, doesn't have a locker, doesn't even have a student folder. Jay almost tells the school -- almost -- but then decides that this lost information could be very...useful. And fun.As Ray and Jay exploit a clerical oversight, they each find new views on friendship, honesty, what it means to be a twin -- and what it means to be yourself.
