This book is 2015 Caldicott Honor Book and it's not hard to see why. This is the story of Peter Roget, the man who gave us Roget's Thesaurus. This book has helped generations find just the right word when necessary and the story of Roget's life from a little boy through adulthood is a sweet one. The illustrations include watercolor, collage and lists all arranged cleverly on the pages. How does someone come to write a Thesaurus? By being fascinated with lists as a child. Roget chose the greek word for "treasure house" for a title for his book and it fits. This book will delight any young artits or wordsmiths and grown ups will learn a few things too. Especially Latin.
