The illustrious George Kelley reviewed this one years ago, but I'm always behind the curve. I did, however, review Wondrous Beginnings, Magical Beginnings, and Horrible Beginnings, all of which are based on the same idea: publishing the first stories of famous authors. In those books, each story was in most cases accompanied by the author's commentary on it. James L. Sutter takes a slightly different approach. Each story is accompanied by an interview with the author, and while the interviews do touch on the stories, they range a little farther afield. Sutter wanted to include in his book writers who weren't in the volumes I mentioned above and who would be available for an interview.
I've commented on at least one of these stories before, Cory Doctorow's "Craphound," a very good first story. China Miéville cheats a little by offering a story that no one knew was his first story. It was published when he was 14 and had heard about but not read Ridley Walker. Considering those two things, it's an amazing piece, and it's pretty amazing on its own, even aside from that. Charles Stross says he didn't want his story to be reprinted and didn't even want to re-read it, but he allowed it, anyway. Several of the writers have amusing anecdotes about how their first stories came about. R. A. Salvatore's comes to mind.
This is another of those books in which the supplementary material is as entertaining as the works it collects. If you enjoy SF or just reading interviews with writers, you'll get a kick out of this one.
