"We all knew no one would stop us if we wandered off, provided we were back by the day and the time we entered into Keffer's ledgerbook" (118). At this point, they know they are clones, and know they will die at a young age, why don't they just buck the system? Has no one thought of doing this? Just my intuition, but I don't think that they were implanted with GPS tracking devices at Hailsham. They have cars, they could just drive off somewhere and never come back. The only problem with that, however, would be their lack of knowledge in the real world. They don't know much about taxes, or leases, or jobs. They could lead a completely normal life if they wanted to, but instead, they chose to donate organs and die at 24. This makes no sense to me.
