Micronauts (Micronauts #10)

As the Micronauts desperately search for the way back to Microspace, Microspace pays them a visit! A horde of Baron Karza's forces invade Earth. Their mission: capture the Micronauts at all costs! But Oz and company are already being chased by shadowy agencies on Earth. Sounds like a clash between bad guys - with them 'Nauts caught in the middle - is on the horizon.
