Lucky Starr and the Oceans of Venus

<b>From the front Flap of the Gregg Press edition:</b> "How can Lou Evans, member of Earth's Council of Science and Lucky Starr's friend, be guilty of treason? Who is trying to steal top-secret Venusian yeast formulas? What on the planet Venus has the terrible power to control men's minds? <p>These are some of the questions that must be answered by Luck Starr, youngest member of the Council of Science, before he can fight the awesome danger to the bubble-like city of Aphrodite, built beneath the Venusian ocean. The entire city is threatened with flooding, spurring the tough young Councilman and his tiny Martian sidekick, Bigman Jones, into action that is soon jet-propelled. A titanic struggle with a monster beneath the eerie ocean waters, Lucky's unique fight to resist mental controls are only two of the thrills in store before all the mysteries are solved and final combat waged with the mysterious evil power."
