Marjorie Sue is both sporty and a girly, girl - rolled into one super - energized, fun lovin' package. Parents of K-3 will appreciate her honest and spirited look at the world of a third grader. It includes lessons about life and social values, as well as age appropriate STEM (Science, Technology, Engineering, and Math) topics. Yet the educational component doesn't outshine the beautifully, playful illustrations and witty storylines, which will keep kids coming back for more. Marjorie Sue children's books
