From the publisher:
Peter Pepperell abruptly stopped growing at the age of 7, after which he started getting smaller. But while his body became tinier, his mind got bigger and so did his sense of adventure. When he learns of an overseas madman who's threatening the world with a compact but powerfully destructive weapon, the 4-inch-high boy climbs on the back of a friendly seagull and heads for Europe to disarm the evil scientist -- and to do a little sightseeing along the way.
