An ALA Notable Book for Children: “The Blossoms are totally real and believable, yet quirky enough to be fun” (School Library Journal).

Junior Blossom has created the most spectacular invention of all time: a homemade UFO. The Green Phantom took all of the garbage bags and Day-Glo paint Junior could find, but now it requires one more very special ingredient. Although Junior needs help, his family seems too busy to notice. Then when Pap and his dog, Mud, don't come home from town, the Blossoms are pulled apart even farther. Are Pap and Mud in serious trouble? Can a Blossom promise bring everyone back together again?

The strength of family love triumphs in this adventurous third title of the best-selling Blossom Family series by Newbery Medal–winning author Betsy Byars.
