Someone Better Than You - Barry Knister

For years, Brady Ritz writes satire about his family and friends under a fake name, but when vanity leads him to publish a collection of his essays under his own name, his wife Natalie leaves him alone in their Naples, Florida golf community. It doesn't matter that what he wrote is often right, or that he concealed people's identities. Once they learn Brady wrote a book, people start reading, and finding themselves.
