Reading the Nebula nominees--The Mothers of Voorhisville is the second one I've read in the novella category. And it's on the long end, nearly a novel. But a good choice for this category and length because, while it is complete as a story it does not read like a novel.
The story is told as a series of vignettes by the Mothers, a group of women who have all been seduced in very short order by a "man" (they are not quite sure later) and have given birth to very unusual - winged - babies. They try to tell their story in their own words, not pulling too many punches but still trying to explain themselves. Voorhisville is a small town, typical in its uniqueness. All the Mothers are well acquainted. Their work in trying to process this utterly strange thing that is occurring to them is fascinating and moving.
I give it three stars overall, and can recommend it as a good read, something to savor.
