“Let’s Not Do That Again” is a political comedy of manners that reads like the love child of Page Six and a long episode of “Veep.”

Virginia Grohl managed to raise the Foo Fighters founder and former Nirvana drummer Dave Grohl—a guy who also happens to be kind and stable and who doesn’t hate her. In a new book, she’s asking other music-industry moms how they did the same thing.

The opening scene is perfection. We meet the eponymous heroine of Diane Johnson’s latest novel, “Lorna Mott Comes Home,” as she rides in the back of a taxi, en route to the train station in Lyon.
