The Family Trade (#1 in The Merchant Princes series) by Charles Stross
Hardcover: 304 pages
Publisher: Tor Books
The Merchant Princes series are alternate history, science fiction stories. Miriam Beckstein is a journalist whose mother died when she was a baby. Now an adult, her adoptive grandmother has given her a box of heirlooms which once belonged to her birth mother. A family locket transports Miriam to a parallel world that never developed beyond the Dark Ages.
This book had a truly unusual concept and it was a pleasure to read, but you don’t have to love science fiction to enjoy this read. The next two books in the series are: The Hidden Family and The Clan Corporate.
