Query: Pages missing

I received "Bald in the Land of Big Hair" book. It was to be a gift. I thought I should read it before giving it to my sister in law, who has cancer. I'm glad I read it. About 50 pages were missing and upon flipping through the rest of the book, another section was duplicated. I did not return the book because it was too much trouble.
