The books work well for reading out loud to kids or for young readers just starting to read by themselves. Written by some of the best-known writers for children, and illustrated in exuberant colour by some of India's most-loved illustrators, these stories are set largely in non-urban settings. Hawaldar Hook is the endearing mascot of the Hook Books. Each book includes short and fun language exercises at the end.
