I hated this. In terms of technical craft, the writing was good and the dialogue was notable. But dear lord, where the fuck was the character development?
I get that this was a collection of narrow, arguably 'defined', focus. Given that, I would have expected more precision and nuance in the telling of so many tales of infidelity, and of unfulfilled middle-aged men chasing young women who they seem to adore out of some idealized obsession with youth and beauty.
Salter doesn't take any time to make these women actual characters (with the exception of Marit in "Last Night.") They seem to serve as mere objects for male wish-fulfillment, chasing one's lost youth, or as mirrors for male ego. (By the way, he doesn't do much with his male protagonists either, more in a moment.) The description of women's bodies throughout the collection is exhaustive, and yet we hear nearly nothing about these women's lives or their own development, and all descriptions of them stay on a surface level. For example:
"She was thirty one, the age when women are past foolishness, though not unfeeling."
"She was twenty-five and filled with life. That summer he saw her in a bathing suit, a bikini. She was stunning, with a kind of glow to her skin. She had a young girl's unself-conscious belly and ran into the waves."
"Westhampton, her tanned legs and pale heels. The feeling she gave him of being younger, even, God help him, debonair."
First off, gross. Secondly, these are the kinds of lazy cliches that are usually abolished in undergraduate creative writing classes - tell me again why I'm supposed to be impressed with a writer who resorts to such sloppy characterizations and can only tell rather than show what is important about these characters? What about the fact that the very information that's being underscored as most remarkable is in fact obvious and unremarkable? You could say that's what Salter is going for, but you'd be giving him too much credit.
Middle age is conflicting. Older men chase youth, often through young women that make them feel vital and younger than their age. The problem with this collection is that Salter never goes further than that. There's no examination of what makes aging so deeply terrifying, of how strange it is to recognize youth for having lived it but to simultaneously realize you are on the other side of it, that you have lived a long time and youth is past, and your life, for all its adventures and tribulations, is not terribly valuable or interesting to young people, though they are very interesting to you. This is the kind of thing writers like Lorrie Moore are able to explore, while Salter leans on hackneyed cliches of marital affairs, without ever exploring the complexities of what drives his respective characters to enter into their affairs. The complexities of married life, for better or worse, are usually glossed over, it's always just "and then I saw this very beautiful young woman (btw, he calls them 'girls' even though they're all 25+, which, ew, way to see women as people and treat them like adults, way to craft protagonists with relatable viewpoints,) and this girl makes me feel alive when I stick my dick in her oh but she's also unattainable, now I feel happiness is unattainable, and ah shit, I kind of liked my marriage and I guess this fucked it up a bit, I am a sad old man and I kind of have a drinking problem." Over. And over.
Though I had a hard time reading so many stories told from the perspective of self-pitying middle-aged alcoholics who don't see women as equal human beings, the collection was mildly entertaining when I could hold back the bile. I didn't want to finish it, but the final story, "Last Night", makes me ever so slightly glad I powered through.
TL;DR: I don't get why anyone thinks this guy is good. Salter's technical eye for dialogue and prose cannot come close to redeeming the outright hackery and cliches that define each story in this ham-fisted collection. Save yourself some trouble and read short that are actually good, like Alix Ohlin's "Signs and Wonders" or Lorrie Moore's "Bark" (which is a much more insightful collection dealing with similar material and conflicts.)
