Query: Another favorite from Crockett Johnson

Our son loves Harold and the Purple Crayon, so we ordered this Trip to the Sky story. At first I didn't find it as clever, but the more we read it, the more our son enjoys it. We love the imaginative exploration, Harold's ingenuity, and the simple yet unique drawings. The move from night to day is wonderfully sudden, and the play with words once again delightful. The dated paranoia about u.f.o.s is amusing to us, and it's the perfect kind of "scary" for a not-quite three-year-old.
