The World Beyond ♦ By Ray Cummings

A grandfather and a scientist travels to a perfect world somewhere in the universe, a heaven, so to speak. No wars, no greed, everything a body or a soul could ever want is provided. On his 21st birthday, the grandson is abducted by beings sent from that world by the grandfather. There is a problem however: Two other "friends" are also abducted, and they are less then honorable. Will the two friends who harbor lust, greed, avarice etc., in their hearts affect this perfect world?
