Sheila Williams has assembled ten stories which have appeared in Asimov's Science Fiction Magazine. This is her 26th collection, so she presumably has the process nailed down. In her introductory chapter, the editor enthuses about the removal of page constraints on an electronic anthology and very briefly describes her rationale for including each of the ten stories. There is a somewhat different reason for each story, rather than a unifying theme.
My favorite three of the ten:
Connie Willis' "Inside Job" is an old-fashioned detective story that might have been written in the first half of the twentieth century. Except there might be some science fiction in it. Rob and Kildy are reporters and professional skeptics trying to demonstrate that a popular medium (yes, the turban-wearing kind) is a fake. It should be easy.
Allen Steele's "The Days Between" is a new perspective on the hibernating-colonists-travel-to-another-solar-system story. Three months into the URSS Alabama's voyage to 47 Ursae Majoris, Leslie Gillis awakes from an unusually short hypersleep. He cannot return to sleep without help and he cannot wake any of the other crew. So he makes the best of it. This story is incorporated into Steele's 2002 novel, Coyote: A Novel of Interstellar Exploration.
Daryl Gregory's "Second Person, Present Tense" is one of those teen identity stories with a bratty, first person narrator. Actually, it's the second person, in the first person. But the first person isn't in there anymore. Much. Anyway, she really hates her parents.
I liked some of these stories and was only moderately engaged by some of them. Gordon Sellar's "Lester Young..." story took readers on a tour of an interesting future solar system but didn't seem to have a point. I got a similar feeling from "Shoes-to-Run." Sara Genge explores a future tribal culture with a story that, ironically for its title, went nowhere. "Breeze from the Stars" had a point, but it didn't seem quite worth the journey.
It all shakes out to this seeming like only an "okay" collection to me. Your tastes may be different than mine. It seems that the editor's tastes differ, too. You may be in good company.
