From the Inside Flap
Fifty years before, the "Peace Authority" took control of governments worldwide with a radically different weapon, the "bobbler," which encased its targets within an impenetrable force field, rendering resistance impotent. After the decimation caused by severe plagues, civilization fell into a semifeudal state, and all high technology was banned.
But Paul Naismith, inventor of the bobbler, has never given up hope, and having hidden from the usurpers for decades, he is finally ready to lead the tinker underground against the evil he helped to create. The odds against them seem impossibly long. Nothing has been able to defeat the Peace Authority's bobbler.
Until now . . .
