How many kinds of green are there? There's the lush green of a forest on a late spring day, the fresh, juicy green of a just-cut lime, the incandescent green of a firefly, and the vivid aquamarine of a tropical sea. In her newest book, Caldecott and Geisel Honor Book author Laura Vaccaro Seeger fashions an homage to a single color and, in doing so, creates a book that will delight and, quite possibly astonish you.
