Wandering Stars is a sci-fi and fantasy anthology themed around Judaism, containing contributions from Isaac Asimov, Robert Silverberg, and Isaac Bashevis Singer. The whole collection was edited by the Australian Jack Dann.
There are at least two stories involving alien converts to Judaism, two others with narrators reminiscent of Tevye the Milkman, and a brilliant love story that inverts life and death. Some of these stories are fairly stereotypical and may prove grating for actual Jews, but then again I don’t really know.
Without hesitation, I recommend this collection to sci-fi devotees.
