The Family Trade is the first book in The Merchant Princes series by Charles Stross. It’s the story of Miriam Beckstein who’s a just-fired tech journalist. In the aftermath of the story that was too big to let her keep her job she discovers she’s a countess as part of a feudal clan in an alternate Earth that she has the rare ability to travel back and forth between.
While that sounds like it could be the basis of a pretty simple fish-out-of-water tale, this is Charlie Stross, so of course Miriam sets out to deal with the world, and change it. The riches of her clan on the other side are based on basically being drug mules on our side. While this is lucrative it’s also vulnerable to market fluctuations (if the war on drugs in the US ended, there would go their wealth and power).
Stross writes characters that are competent and resilient and generally deal with things so you can get to the next idea. It keeps the plot moving when you don’t have to wait ages for a character to figure out some problem the reader saw the answer to as soon as it was proposed. The grander idea of “how will Miriam reshape her clan’s economy” is an idea you want to puzzle over, and the main reason I’m going to be resolutely avoiding spoilers from here on out. I’ve read the background on how this series got split into volumes kind of weirdly and yeah, it’s pretty noticeable, since this book ends kind of right in the middle of things happening.
Good light, fast-moving stuff. I’m looking forward to the next book.
