Through a mishap in Professor Bulfinch's laboratory, Danny accidentally creates an anti-gravity paint.

A mechanical failure dooms the four to a one-way trip out of the Solar System -- unless they can repair the spaceship in time!

Look for "Danny Dunn on a Desert Island," the second volume of the series, coming soon from Wildside Press!
