Thumb Thumb books is a unique reading series created around the commonplace thumbprint. Words and pictures tell simple stories, sometimes with unexpected twists, featuring Thumb Thumb Thambi and Thumb Thumb Thangi and their world of thumprints.

The books use words from a child's rich and spontaneous spoken vocabulary rather than from the formal, graded one. Short sentences, bold type and vibrant pictures make reading effortless and enchanting. At the end of the story, children are encouraged to make drawings using their own thumbprints and feel at home in the page the line, 'I can read this book'. Each time a child reads this out aloud, it affirms the young reader's place in the world of books.
