The Merchant Princes Series

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).

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; the sequels may or may not eventually be written.

This series provides examples of:

 * Action Mom (Miriam's "adopted mom" has a shotgun hidden in her wheelchair. Seriously.)
 * Alternate History (each AU has a place where they diverged from normal Earth)
 * Miriam's Earth is also slightly alternate, as revealed in Book 5. Chemical Ali killed Saddam Hussein before the Iraq War even began.
 * Alternate Universe (and there isn't just one)
 * It's worth noting that the series is quite a brutal Deconstruction of the usual "Alternate Universe" setting. The logistical and geopolitical consequences are explored quite thoroughly.
 * Action Girl (slightly subverted - Miriam can't take anyone down during a fight, but she sure shoots people who try to kill her and doesn't wait to be rescued)
 * Brilliana and Olga, on the other hand, have no such limitations.
 * Anyone Can Die: Just saying.
 * Arranged Marriage (Both Miriam and her mother. Neither were happy about it at all.)
 * Badass Normal (Miriam's friend Paulette, everyone in Clan Security, Mike Fleming)
 * Ballroom Blitz
 * Beware the Nice Ones (They might actually be intelligence service!)
 * Big Damn Heroes (Brilliana and the rest of The Cavalry show up Just in Time to save Miriams and Erasmus's ass at the ticket office stand-off in Book 5.)
 * Big Screwed Up Family (the entire series is the epitome of this trope)
 * Changeling Fantasy (deconstructed harshly: Miriam is secretly a noblewoman with magical powers from a medieval-type world, and it sucks. Also in that )
 * The Chessmaster
 * Conspiracy Redemption
 * Convenient Miscarriage: somewhat subverted in that in some ways, it isn't all that convenient. Nice for  personally, not so much for politics.
 * Deliberate Values Dissonance (the people of the Gruinmarkt and New Britain don't think like modern Americans, and Miriam really doesn't like having to play by Gruinmarkt rules)
 * The Ditz (Olga is set up as this in the first book, but it's really a case of Obfuscating Stupidity. Kara, on the other hand, is a straight example.)
 * The Don (Duke Angbard fits the role)
 * Doom Magnet: Dear innocent bystanders, stay the hell out of range of Miriam (or the other plot lines for that matter) if you want to live. "Within range" means
 * Evil Chancellor (Matthias, )
 * Evil Matriarch (Miriam's grandmother)
 * The Evil Prince: Prince Egon aka "The Pervert".
 * External Combustion (Played straight with in Book 5.
 * Family Unfriendly Aesop (There's nothing wrong with a little responsible use of drugs; not just alcohol, but marijuana and crystal meth.)
 * Even/especially if you're pregnant!
 * Feuding Families (there was even a civil war 30 years ago, and Miriam's return threatens to start it up again)
 * Gambit Pileup (By the third book, there are at least five different factions all either shooting at each other or inches away from doing so.)
 * Lampshaded when Miriam, in the second book, asks whether there's anyone in her entourage not working for the secret service. Her maid Kara responds, "Not me!"
 * Genre Shift: It starts out exhibiting more fantasy tropes (noble families in Medieval Stasis; magical-seeming phenomena mediated through a Celtic-knotwork–style sigil), but by the midpoint the series is clearly economic and military science fiction. This is in part the result of Executive Meddling: one publisher already had an option on Stross's next SF novel, so he started this series as fantasy in order to be able to get it published by another company.
 * Giving Radio to The Romans: How Miriam gets rich in New Britain.
 * This trope is Zig Zagged. They consider it, and ultimately everyone agrees to support if that's what she wants, which is surprising in the socially conservative culture of the Gruinmarkt. That's justified by both an inversion of Politically Correct History - people actually do understand the value of that kind of thing, because in that kind of culture it can prevent blood feuds and Death By Childbirth - and a possible Batman Gambit.
 * Invisible President—sort of. Although George Bush and Dick Cheney appear as characters on-page occasionally, their names are never used (except for on one page near the very end of Book 6 ), even though names of other public figures, such as Ashcroft and Scalia, are used more or less freely. The text, and all the other characters (even those for whom it makes no sense to do so), refer to the president and vice president by their supposed CIA code names, BOY WONDER and WARBUCKS.
 * Kissing Cousins (because the dimension-hopping is genetically recessive, the family is braided - people have to marry other clan members in order to ensure the children inherit it, but to avoid inbreeding, those family members can't be too closely related. There are a lot of second-cousin or first-cousin-once-removed marriages)
 * La Résistance (The Levelers in New Britain.
 * Les Yay (Miriam and Brilliana get plenty of subtext. Brilliana even kisses Miriam at one point, though that's probably not intended to come off as sexual.)
 * Loads and Loads of Characters
 * Mad Doctor ( - not actually mad, but definitely completely unethical and outright creepy)
 * Magnificent Bastard (Miriam's uncle and )
 * Medical Rape and Impregnate:
 * Mighty Whitey (Miriam tries this, but her plans get repeatedly derailed because she gets caught in everyone else's byplay.)
 * Misapplied Phlebotinum: A minor version is played straight at first, and a major part of the plot is ending that. The Clan has the ability to teleport between worlds, and they are using it to get rich by smuggling drugs past international boundaries and selling high-tech innovations to a low-tech setting. However, the system used at the start of the story is limited to what individuals can carry and it's unsafe to make trips more than once or twice a day, putting a sharp limit on the weight and volume of their interdimensional cargo. And trade is risky for cultural reasons (such as illegality) in both worlds. After Miriam throws a Spanner in The Works, people begin experimenting and work out ways to increase the amount carried, and she suggests that Giving Radio to The Romans would be a much higher-profit enterprise, given starter capital and a government that enforces patents.
 * Obfuscating Stupidity (Olga tends to play the Dumb Blonde stereotype in social situations)
 * Brilliana's just an ordinary serving girl. She's not a wannabe marine turned secret police for the Clan, no sir.
 * President Evil
 * turns out to be even worse.
 * Properly Paranoid (A repeated motif is various characters being very careful when opening doors or entering houses - a wise decision, given the amount of booby traps in the series so far...)
 * Run or Die (after Plan Blue goes through, the progressive faction of the Clan realizes they have a very limited amount of time to get the hell out of Dodge.)
 * SheKnowsTooMuch (Miriam is a journalist and tends to dig, which gets her in serious trouble on more than one occasion)
 * Shout Out: The end of The Trade of Queens has one to Clarke's "The Nine Billion Names of God", of all things:
 * turns out to be even worse.

 * On a lighter note, Miriam's friend who happens to have some legal training usually has some words of wisdom, often a bit off kilter, which she prefaces with "As your attorney I advise you to..."
 * Pirates Of Penzance: The general was the perfect model of a modern military man
 * Squee (Executed and named hilariously in The Merchants' War. ("SQUUEEEEEEEE!"))
 * Schizo Tech: The Clan create schizo tech wherever they go. In addition, New Britain has minor elements of it all by itself.
 * Science Cannot Comprehend Phlebotinum: Averted - the Clan firmly believe that their world-walking ability is a unique power that nobody else can duplicate, but.
 * Spanner in The Works (Miriam's very existence knocks several conspiracies out of the water, and then she brings her reform plan into play)
 * Steampunk: New Britain has elements of this, with zeppelins and trains being bigger and more important than they are now in real life, but cars and planes never took off.
 * Teleport Interdiction - the antagonist in The Merchants' War strings ropes all over his castle to keep out the world-walkers.
 * There Is No Kill Like Overkill: Played dead straight with Operation CARTHAGE. No One Could Survive That for real.
 * The Unfavourite (Miriam is often an outcast, since she lived for so long in her Earth)
 * Wham Chapter: At least one per book, but then Books 5 and 6 turn it Up to Eleven.
 * Xanatos Roulette
 * Xanatos Speed Chess: Massive multiplayer edition.
 * Seriously, almost all of the many characters get caught up knee-deep in intrigue and hatch their own elaborate plans. Predictably, everything starts going to hell very fast, and that's just the beginning...
