Davis is very funny, in the English-country-house comedy-of-manners tradition--on the tour itself, making free with the unsavory combination of precious historicizing and raw sexual tension that characterizes such holidays. And she may well have a thing about vegetarians, who are well represented. 'St. David's? Most Welsh churches seemed to be named for him, a man who subsisted on leeks and water and caused a hill to grow under his feet so he could address his disciples from a lofty position, more or less in the spirit of modern-day vegetarians.' The satire jostles along nicely, full of prickly insults and off-balance observations.

Bobby Rose and Coleman Snow, the two husbands, run a company, SnowWhite & RoseRead, that has invented a kind of overwriting device, a computer program that detects vulnerability in texts and allows readers to rewrite them. This program may or may not have precipitated a kind of holocaust of meaning, where Susan is forced to dwell now that her parents have quit the scene. If this all sounds a little vague, it is. In retrospect, Susan muses, 'But how did it work, I wonder? By which I mean, morally, not technically. What came over people that they'd let other people fool around with their words, their sentences, their ideas, their dreams?' Dunno, but at a certain point, one starts to wonder how it worked technically, not morally. Don't expect a punch-line, end-of-novel answer, for it never comes. Davis hangs a huge amount of millennial, late-capitalist baggage from this invention, and yet we never properly find out what exactly it is. You can make out the kernel, just barely, within the mist. But the mist starts to give you a headache, and you yearn to get back to the really rather good yarn of the four people going for a walk in Wales. On the other hand, a headachy mist is just the effect Davis seems to be after in her fourth novel. For readers seeking to be unmoored, this is a heady, misty read indeed. --Claire Dederer
