Tom Swift and His Sonic Silentenna (The TOM SWIFT LIVES! Adventures)

A weird blast of sound engulfs an American city. Tom Swift, demonstrating his newest invention at a noise reduction conference, is caught up in the terror and destruction — and mystery.It seems the sonic attackers, who descend from the sky with with drone sound-boomers, are somehow connected to the disappearance of Dr. John Wyvern, whose daughter Elsa has come to Tom for help. Tom ferrets out a clue with the aid of his robotic “bloodhound,” the sensi- tector. One clue leads to another, and the trail points to the great Australian Outback, where an entire tribal family has vanished without a trace under eerie, inexplicable circumstances.Yet as the terror attacks on American cities continue, it seems the only hope is Tom’s sonic silentenna, a revolutionary device able to neutralize sound. One attack is foiled dramatically — but the key to defeating a brazen threat may lie in the Australian desert, where blazing fire and the warning wail of the didjeridoo horn signify danger and death!
