Neo returned to reading one of his favourite authors, having recently discovered this new piece to the Mo Willems collection. When a number of squirrels gather together to take a walk, they come across a mysterious sign they cannot read. Enter the Mystery Reader, complete with mask and matching underpants. Through some efforts, Mystery Reader teaches the others to sound out the word, without revealing themselves. As the book progresses, the reader is able to learn a few “acorn-y” jokes, as well as the history of reading and books. A great educational piece that Neo hopes many others will read, given the chance.
