The Great Dictionary Caper by Judy Sierra; illustrated by Eric Comstock. 2018. Digital. Published by Simon & Schuster Books for Young Readers.
Brief summary: Grand Marshall, I, tries to get everyone ready for a parade but has trouble with the longest word(see if you can guess what it is), action verbs, no action contractions, homophones, antonyms, palindrome, archaic words, proper nouns, anagrams, interjections, and others to get back into the dictionary with the help of Noah Webster(first dictionary) and Peter Mark Roget(thesaurus).
Comments: Glossary in the back. This actually will be better understood by the older young reader who can understand and is familiar with all the types of word categories. I would share this with third grade on up.
