The reluctant hero of this hilarious novel is John Oliver Banion, a stuffy Washington talk-show host, whose privileged life is thrown into upheaval when aliens abduct him from his exclusive country-club golf course. But were his gray-skinned captors aliens...or something far more sinister? After Banion is abducted again - this time in Palm Springs - he believes he has been chosen by the extraterrestrials to champion the most important cause of the millennium, and he embarks on a crusade, appearing before a convention of UFO believers and demanding that Congress and the White House seriously investigate UFOs. His friends and family suspect that Banion is having some kind of manic-depressive midlife crisis and urge him to seek therapy before his credibility as a pillar of the punditocracy is ruined. So John Oliver Banion must choose: keep his establishment status or become the leader of millions of impassioned and somewhat scruffy new friends who want to expose the government's secret alien agenda.
