The Sunken World

A GIANT PASSENGER ROCKET... hurtling through space on a plume of flame... bound for the Moon. That would have sounded fantastic only yesterday—but today it is possible—because fuel for such a trip is available NOW. Scientists have learned how to develop and control almost unlimited power by splitting the atom. Shortly there will come within range new planets, Venus, Saturn, Mars. We already know a great deal about the conditions and climates on these which may give rise to new ways of life. In Fantasy Books, a new type of thriller, you will find these facts set out in fascinating details and woven into stories and adventures of an entirely refreshing kind.
