This is #15 in the Tor double series from 1988 to 1991, although both novellas originally saw print in the late 1960s. I’m pretty sure I’ve read them many years before, either in a collection or Ace double (which is how the Vance was originally published). Silverberg also expanded ‘Nightwings’ to novel-length, and I may have read that too. I can’t remember – and, to be honest, I can’t recall much of ‘Nightwings’ only a couple of weeks after reading it. Vance’s ‘The Last Castle’ is at least more memorable. It’s set during the twilight years of Earth, after humans from another world decide to recolonise it, and they now live a life of ease in castles, waited upon by alien creatures called ”. Who promptly decide to kill all the humans. Only one man takes the threat seriously enough to attempt to fight back. It’s typical Vance in all respects, and as fair an introduction to his oeuvre as any. There are, sadly, only two female characters named in the entire novella, and they’re wives and sex partners. Even for 1966, that’s piss-poor. Silverberg’s novella actually features a female protagonist – she’s the “nightwings” of the title, a member of a race adapted from human stock for flying. She travels to Rome in some distant future in the company of the narrator, a Watcher, and a mysterious man who seems somewhat too well-educated to be the non-guild itinerant he claims. A Watcher, incidentally, is a member of a guild dedicated to scanning the galaxy with some sort of equipment built into a small cart – it’s all very vague and handwavey – in order to spot the first signs of a long-threatened invasion. Which, of course, happens during the story – well, there’d be even less of a plot if it hadn’t occurred. ‘Nightwings’ won the Hugo, and was nominated for the Nebula, in 1969, but I thought it pretty slight. It trades entirely on atmosphere, despite the fact little of the background makes sense, and the ending is visible from several kilometres away. Meh. ( )

Amazing to think that when they published this TOR Double, Vance was listed over Silverberg as the first author. Note that there is also a novel by Silverberg with this same name, but it includes two additional works, and is different.

Both Nightwings and The Last Castle had been originally published in Galaxy magazine; Nightwings in 1968, and Castle in 1966. Both are dying earth sorts of stories. ( )
