Take cover! The mad, mad, Mad Scientists' Club of Mammoth Falls is back in action.

Since the publication of the Bertand Brinley's first book, The Mad Scientists' Club, strange things have been happening. Mad Scientists' clubs have sprouted up, kids and grownups alike have been eagerly reading these incredible adventures, and the persistent, popular demand has been for more adventures!

So our seven young scientists, complete with clubhouse, electronic gear, and wild, weird schemes are back again with flying saucers, electronic crime detection, seismographs, rockets, weather control, submarines (for real!) and well, you won't believe it until you read it.

Too bad the good and stalwart citizens of Mammoth Falls, university professors, the Air Force and even the Pentagon are sometimes unappreciative of our heroic, creative little group. But then, they were never real scientific geniuses like us, either.

"[T]his reissue...reintroduces a brotherhood of boy geniuses with a penchant for electronic crime detection and advanced rocketry." Smithsonian Magazine, Notable Books for Children 2002

"[F]illed with spirit of adventure and good-natured fun....In fact, Henry Mulligan, chief Mad Scientist, reminds me of me!" Homer Hickam, author of October Sky

The six members of the Mad Scientists' Club experiment with new projects which include making rain and launching a flying saucer.

Just another quiet day in Mammoth Falls. Or is it? Have flying saucers really been sighted? How about those rumblings in the ground during the wee hours of the morning...and a midget submarine hidden in a secret cavern?

With evidence like this, our seven young geniuses can't be far behind. And they're not! The town of Mammoth Falls will never be the same again, because here come the Mad Scientists with five more mad adventures!

Stories in this volume: "The Telltale Transmitter," "The Cool Cavern," "Big Chief Rainmaker," "The Flying Sorcerer," and "The Great Confrontation."
