Every so often, men contact the author complaining that his books use both male and female pronouns. This special edition, using only male third person pronouns, is for those special people. As the market is so much smaller, it’s unfortunately priced higher.



For each copy of the Manly McManface edition sold, the author will donate one dollar to his local chapter of Soroptomists International.
