With over half a million copies in print, Mortimer is one of Robert Munsch’s most popular and beloved books.

Mortimer is the story “... of a little boy who won’t go to sleep at night and who drives his family crazy with his rowdiness ... [It] reads as though it was written by a parent driven frantic by one of the contemporary but compulsive stages of childrearing ... [It is] of tremendous appeal to kids and parents at the same stage.”—Globe and Mail
