The Clan Corporate

Good book. But, definately not a stand-alone novel. This is the middle volume of the reedited and reissued omnibus editions of Charlie Stross's Merchant Princes stories. (This one combines The Clan Corporate and The Merchants' War.) The Bloodline Feud should be read before The Traders' War and it will be necessary to read The Revolution Trade to finish the story.
What's it all about? Well, there are alternate Earths with histories that differ from our own. And, there are some people, a small related group, that have a genetic mutation that allows them to “walk” between the worlds. This trilogy is the story of their intrigues, conflicts, power struggles, and romances. The story is fast-paced and very entertaining, and I found some of the characters to be quite likeable.
