 Flash, Dale, and Dr. Zarkov return from their former space adventures only to find that their enemy, Ming the Merciless of planet Mongo, has a new weapon: a deadly ray that crosses space to wreak havoc on earth. Earth s only hope is for our heroes to take off again and stop the ray at its source on Mars, where they (and a stowaway) must battle Ming s ally, Queen Azura, who turns her enemies into lumpish clay people. Can they survive 15 chapters of deadly perils? Find out next week...
