I've finally caved in and changed the subtitle of On Herring Cove Road: Mr. Jew and the Goy Boy to On Herring Cove Road: Mr. Rosen and His 43Lb Anxiety. After doing a search and seeing people taking the the title as being racist, I decided it was best to make the change. Originally meant as tongue-in-cheek since the title is explained in the third chapter by nine-year-old Dewey's confusion, my error as the writer of the novel seems to be that readers wouldn't get the innocence of the subtitle unless they first read the book.
I had to give the subtitle some serious consideration before committing to its audiobook, which is coming out this next week.
