Its about a group of friends that all live together in the future. The world is very crime laden and starving to death. They are all educated; they receive a invite to go to a building. When they get there they don't really receive any greeting, only they are asked to sit in these chairs. Then when they open their eyes they are in a new world, they go out and explore it. If they get into danger they are instantly brought back to their world. The more and more they go there the longer they are left there dispite injuries. Eventually they are told they are meant to inhabit this new planet with all of their skills and education. They find another group and start a new colony. I also remember they are sent there in a biodegradable translucent egg like thing. Any information on this would be great! Btw I read this book in highschool if that helps.
