Good Luck Chestnut is a picture book full of colorful horses and colorful kids. In theory, the watercolor paintings illustrate horse colors, but in practice, they also capture the way children use horses as jungle gyms and playgrounds. The children sit backwards, hop on by leapfrogging, belly-flop off the horse into water, everything but sit forward in a saddle, riding-lesson proper. The names of horse colors are embedded in the text, while the various nationalities of the children visually round out the book’s concept. Any child should find themselves somewhere in the illustrations. This book is just yearning to be read aloud. The whole thing is a rollercoaster of rollicking slant rhymes hurtling itself toward the last simple message that every child deserves to hear.
