Ray and Jay Grayson, identical twins, are relocating to a new community. Again. But at least they will be able to socialise at their new school with one another. Nevertheless, Ray misses the first day of sixth grade because he is sick, and Jay rapidly realises a serious error: Nobody is aware of his brother. Ray does not have a locker or even a student folder, and he is not shown on the attendance lists. Jay determines that this missing data might be very...useful and fun. Even a little risky, perhaps. These two cunning youngsters learn new ideas on selfhood, friendship, and honesty as they take advantage of an administrative error.
