And here it is. Not easy to find. Some public libraries will have it. Some banned it long ago, and perhaps no one there remembers why.
Forever Panting, one of my all-time faves, was first published in 1973. The godfather of boychik lit, De Vries is hopelessly politically incorrect these days. For example, his Slouching Towards Kalamazoo is about a high-school boy who runs away with his comely teacher. You simply cannot go there now, so have life and lawsuits imitated art in the years since.
Raised in a Christian fundamentalist Dutch Reformed family in Chicago, De Vries held notions of humor that typically involved religious hypocrisy and suburban adultery. His Mackerel Plaza is about a widower minister whose late wife was so saintly and highly regarded, he fears her reputation might get in the way of his plans to marry the church secretary.
