This is book number 4 in the Merchant Princes series.
The story of the worldwalkers just got stranger in Charles Stross's The Merchants' War. More worlds, more surprises. And there's a war going on ...
Miriam Beckstein is a young, hip, business journalist in Boston. She discovered in The Family Trade and The Hidden Family that her family came from an alternate reality, that she was very well-connected, and that her family was too much like the mafia for comfort. She found herself caught in a family trap in The Clan Corporate and betrothed to a brain-damaged prince, and then all hell broke loose.
Now, in The Merchants' War, Miriam has escaped to yet another world and remains in hiding from both the Clan and their opponents. There is a nasty shooting war going on in the Gruinmarkt world of the Clan, and we know something that Miriam does not; something that she's really going to hate--if she lives long enough to find out.
“For sheer inventiveness and energy, this cliffhanger-riddled serial remains difficult to top.” —Publishers Weekly
“The world-building in this series is simply superb, in other words it is engaging, crystal-clear and disturbingly real..... The Merchants' War is fast-paced and engrossing and will leave readers ravenous for the next installment.” —SciFi.com
“Charlie Stross' latest is a brilliant, amusing, and challenging piece of mestizo fiction -- recklessly cross-breeding fantasy and SF tropes, and using the resulting bonfire to say interesting things about culture, economics, politics, and really cool battles with chain-mail and MP5's and horses and hang-gliders. Very real people with very different backgrounds meet and collide and strike lovely sparks. This series is great and getting better all the time!” —S.M. Stirling
“The action shifts rapidly among the three worlds in the fourth successive thriller in a fantastically thrilling series.” —Booklist
