The art is simple, just the black letter with white eyes and mouth, and gray mouse with her pink ears and checked bowtie. M is often part of the words of his half of the story, and sometimes those words are shown in a light gray font. The mouse has cheerful red dialogue and gradually the two share their words until they end with the sweet sentiment that there can't be a mouse with an M.
The art is clever and the story ingenious. It doesn't quite have the appeal of the other alphabet books I've used in storytime or recently reviewed - Trasler's Caveman, McDonnell's Little Red Cat who ran away, or silly favorites like Kelly Bingham's Z is for Moose - but it's quite a good debut effort. It's not quite an alphabet book, with the consonants moving in random order as the M transforms and there are some mildly creepy moments, when the mouse first starts eating the M for example.
Verdict: If you need more quirky alphabet books, consider this a good addition to your collection. Otherwise, stick with the staples.
