Level 2 DK Readers are for children who have started to read on their own, but still need some help. These books contain more words, more complex stories, and smaller type than Level 1. They use slightly longer sentences that are still simple in construction. Information boxes provide lots of extra fun facts.

DK Readers combine an enticing visual layout with high-interest, easy-to-read stories to captivate and delight young bookworms who are just getting started. Written by leading children's authors and compiled in consultation with literacy experts, these engaging books build reader confidence along with a lifelong appreciation for nonfiction, classic stories, and biographies.
