Persistent pet owners and prehistoric pedants of all ages will love this laugh-out-loud story of one kid's tireless mission to bring his biggest best friend to the most brilliant place on earth: the public library! Once upon a time there was a boy who presented a well-thought out proposal for his teacher, Ms. Johnson, convincing her that bringing a pterodactyl to school would be a good idea. The boy is back, and this time he has several reasons why bringing a woolly mammoth to the library would be advantageous to the librarian, Ms. Reeder, and the library's patrons.
