When Robert Grandon swapped bodies with a prince of the planet Venus, he was concerned only with the thrill and interest of living on a different world. But the situation he found himself in was hardly that of a leisurely sightseer. Instead he found himself smack in the center of a whirlwind of intrigue, danger and desperation. PLANET OF PERIL is a science-fiction adventure on a world of semi-barbaric nations, ferocious beasts, gigantic reptiles and maidens in distress.

The Prince of Peril – Using his secret method Dr. Morgan projects a young Martian's astral body into a certain Harry Thorne on Earth, who then gets transported to an ancient Venus. He arrives there in the body of Prince Zinlo of Olba, and he is soon forced to escape assassination, since an ambitious noble is killing off the Royals in a bid to seize the throne. With the help of the fellow interplanetary traveler Vorn Vangal he gets to know the planet and the rules of it.

In Swordsman of Mars, Harry Thorne, outcast scion of a wealthy East Coast family, seeks the greatest adventure of his life.
