Puffin Young Readers Welcome to Puffin Young Readers! As parents and educators, you know that each child develops at his or her own pace-in terms of speech, critical thinking, and, of course, reading. Puffin Young Readers recognizes this fact. As a result, each Puffin Young Readers book is assigned a traditional easy-to-read level (1-4) as well as a Guided Reading Level (A-P). Both of these systems will help you choose the right book for your child. Please refer to the back of each book for specific leveling information. Puffin Young Readers features esteemed authors and illustrators, stories about favorite characters, fascinating nonfiction, and more!
