A Fantasy series by Charles Stross, about a journalist named Miriam Beckstein who finds an Alternate Universe stuck in Medieval Stasis where her long-lost family are powerful traders who can travel between dimensions. There are six books so far: The Family Trade (2004), The Hidden Family (2005), The Clan Corporate (2006), The Merchants' War (2007), The Revolution Business (2009), and The Trade of Queens (2010). A new edition is in preparation that combines them into three volumes (The Bloodline Feud, The Traders War, and The Revolution Trade), with some minor changes to the text.The series was originally planned as four very long books, but the publisher got cold feet about the length of the books and insisted they be broken up into multiple volumes. The six books published so far started out as the first two books of the original plan. Stross revealed in his blog that he plans to start work on the "next generation" sequels soon.
