Exploring the boundaries of the genre, Bova not only writes of spaceships, aliens, and time travel in most of his titles, but also speculates on the beginnings of science fiction in “Scheherazade and the Storytellers,” as well as the morality of man in “The Angel’s Gift.” Stories such as “The Café Coup” and “We’ll Always Have Paris” dip into speculative historical fiction, asking questions about what would happen if someone could change history for the better. This expansive collection is a key addition for Bova fans and sci-fi lovers alike!
