When Jack Goes Out (The Jack Series)
The fifth book in the Jack series brings back the friendly aliens who first appeared in Jack and the Night Visitors (2006). Jack the dog, chained to his doghouse for the night, looks a bit lonely until he notices the tiny, robotic aliens leaving their space car, cavorting about, and unhooking his chain. He joins in their high-spirited play in the sandbox and the pond. When they fly away, they attempt to take Jack with them. From front endpapers to back, each appealing illustration moves the story forward and offers details for children to enjoy. A satisfying wordless picture book. Preschool-Kindergarten. --Carolyn Phelan
