This book is one of a series of Tor double books consisting of two novellas. Turn the book around and upside down, one sees the book cover for the other novella.
I bought the book mostly for the Brian W. Aldiss novella, "The Saliva Tree," and it indeed was the better story. An invisible alien spaceship has crash-landed, or maybe just landed, on to a rural farm in northeastern England in the 1890s. The aliens are invisible, but definitely have a physical presence, and they are not at all friendly or communicative. All of the creatures on the farm are viewed as a source of food by them, including the people. The novel is a realistic portrayal of a farm family and their neighborhood slowly coming to terms with and making plans to confront what is going on.
The novella is an enjoyable, suspenseful enough read. But something is missing. There's a layer of complexity that needs to be there to make this a great story that simply isn't. Perhaps we need to know more about the aliens and their motivations. Maybe we need to see the humans struggle more, see how this first contact impacts them better. It's odd omissions throughout the story that keep it from reaching its potential heights. Still, reading it is not a complete waste of time.
The other story, Robert Silverberg's "Born with the Dead," was slightly longer, 96 text pages as opposed to 87. It won a Nebula, apparently, but I wasn't impressed. The genre is not science fiction, unless one considers the completely unexplained technique of reanimating dead people soon after they die science. I don't call it fantasy because I don't believe any magic is involved. I think it fits best into the weird fiction genre because we are dealing with an alternate Earth of sorts. People all throughout the twentieth century can and have been getting reanimated from a death state in this novella, and doing so at their option. This is clearly not an event that happened any time in our twentieth century. The difference is not explained, just assumed, placing this story firmly in the weird genre.
The premise is that a woman has transitioned into a dead. That's the noun the story uses to label reanimated people who have died. Deads are very different people than their former selves. A loving husband who is still alive can't accept that his wife who is now a dead no longer has feelings for him. He can't live without her apparently and tries to demand answers from his now changed former wife. His former wife and the new community of deads she is a part of consider him to be a pest. This is the story of how that conflict gets resolved.
The story was okay, but seemed to lack point. What's the take-away, the theme? Why did the author feel anyone needed to read it, or what was one expected to get out of it? It feels like a chronicle of events that could never transpire related for no overall purpose or statement. At least, I couldn't find one. Recommended for people who really get into off-beat, original zombie stories. That's not me.
