Barry and Harry are twins, but Barry is strong and popular, and he bullies Harry, who is weak. Harry, eventually getting fed up, locks himself inside a room that holds a singularity, where time flies inside the room while time slows to a crawl outside. He keeps himself in the room for a year while a night passes on the outside world.
The best part of Singularity is not the psychological rivalry between the twins, but how Harry managed to keep himself sane through a regimented routine of diet, exercise, meditation and reading. It is very interesting how someone could find inner peace, and grow up to be a man, through such a regimented, solitary program.
For ages 12 and up.
