Use the five-finger rule to choose an appropriately challenging book and deliver a short, genuine book talk without spoiling the ending.
The five-finger rule helps you choose a "just-right" book: open to any page, read it, and put up one finger for each word that is unfamiliar or tricky. Zero to one finger usually means the book is too easy. Two to four fingers means it is just right. Five or more usually means it is too hard for now -- save it for later.
