Through a mishap in Professor Bulfinch's laboratory, Danny accidentally creates an anti-gravity paint. The natural use, of course, is for a spaceship—the paint can replace rockets to get the ship into space. Unfortunately, the spaceship is launched prematurely after Danny and Joe follow Professor Bulfinch and Dr. Grimes on a tour of the ship. A mechanical failure dooms the four to a one-way trip out of the Solar System—unless they can repair the spaceship in time!
This is the first of the 15-volume Danny Dunn series and features the original cover by acclaimed artist Ezra Jack Keats. Look for Danny Dunn on a Desert Island, the second volume of the series, coming soon from Wildside Press!
