Two very imaginative stories set on a train that changes from mechanical to magical as it travels to different places around the globe. This is part of the Stellar Guild series which pairs an established SciFi author with a protegee, in this case Harry Turtledove and his daughter Rachel. I didn’t think Turtledove senior’s contribution was as good as what I've read in his Timeline-191 series but daughter Rachel’s story more than made up for my disappointment. ( )
