This is not one of Lois Bujold's profound, heart-tearing efforts--but it's fun, and funny, and it's a joy to see Ivan, who is usually overshadowed by his brilliant (and crazy) cousin Miles, shine. Captain Vorpatril's Alliance builds on the glimpses we had, in Memory and in Civil Campaign, of the real Ivan Vorpatril: a man who is just as highly intelligent as his insane Vorkosigan relatives but...less insane. He likes a quiet life. He likes a job that does not require huge shots of adrenalin, or people trying to kill him, or having to produce insane, last minute plans to save everybody. He likes flowcharts, not practical applications of chaos theory. In short, Ivan Vorpatril likes order, organization, and keeping things neat. Where his cousin(s) are masters of chaos and on-the-fly brilliance, he is a master of the orderly.
Beware of spoilers below!!!
Naturally, that gets shot to hell--in a small way--in this novel. And Ivan proves that he is not without a share of the family ability to produce insane-plans-that-turn-out-brilliant-in-the-long-run: when placed into a situation that, on a smaller scale, greatly resembles some of Miles's, he panics, and then produces a workable, spur of the moment solution. It's not a particularly original plan--in fact it comprises the plot of any number of romance novels, ie, marry the heroine in order to save her from some worse fate/help her out of trouble. What turns this on its head a bit, however, is the fact that there is, overall, a notable lack of angst. To be sure, Ivan is faced with a little bit when he realizes that, despite years of avoiding it, he quite likes being married, and to his wife in particular, and he ends up with a bit of worry over whether or not he can convince her to stay put. She has some of the same angst, and like previous Vorkosigan saga heroines who are not Cordelia, she has Relatives, and they are a Pain. (Loveable, but a Pain.)
Insofar as suspense goes, there really isn't much in the book. Because it's set a good six years before Cryoburn, we all know that Ivan gets out of any serious danger. (I'm racking my brain though--I've only read Cryoburn once so far--and I don't recall there being any hints in there about the events of this book. But as it's about Miles, and as it's six years down the road, well...there may not be. It's not as though the Vorkosigan books were written in order, after all.) And, considering the light, fluffy fare of Alliance here, it's really a very good thing that it's not set after Cryoburn, as one would expect any follow-up to THAT one to deal with the bombshell dropped at its end. It's fairly clear, too, that things will work out for Ivan, despite his romantic frustration as we last saw it in A Civil Campaign. Like his uncle, he had better luck in marrying a galactic--and unlike Miles, he had no trouble convincing her to stay on Barrayar.
Some reviews I have seen found Tej to be a bit mild and boring and unworthy of Ivan. I have to disagree, at least on the boring and unworthy-of-Ivan part. Granted, compared to most of the Amazons that Miles tended to hook up with--and even bearing in mind her quiet nature, Ekaterin is still a warrior woman, albeit of the Vor type--Tej is a bit "dull." She is somewhat amazonian in build, being (so I gathered) about six feet tall (or very close to it) and with a distinctly generous figure (hooray for another Bujold heroine who is NOT skinny!). But one must remember that Ivan is NOT Miles. Ivan likes order, and stability, and organization, remember? I think many of us (and I admit to falling for it myself from time to time) often forget that Ivan is not, in fact, an adrenaline junkie like Miles. To be sure, he popped up in many of Miles's insane adventures, particularly early in their careers, and he pulled through more than adequately. And no one can fault his brilliant method of dealing with depressed Miles in Memory, when Ivan hauled Duv Galeni (an extremely dubious and half-terrified Galeni) in to shock Miles out of his funk. But Ivan has never, over the course of the books, stopped voicing his dislike of being dragged into Miles's messes. He still, more than a decade after the events of Brothers in Arms, loathes dark enclosed wet spaces (and it isn't claustrophobia, dammit! It's a perfectly reasonable fear!). He still clings happily to his job as a "secretary" (albeit at this point its for the head of Barrayaran Military Ops, arguably one of the single most important positions in the empire)and does his damndest to avoid promotion (which brings with it jobs that do not entail organization and flowcharts). It makes sense, therefore, that Ivan would fall in love with a woman who comes from an extremely colorful family of overachievers but who herself would really like to be left alone to pursue quiet, calmer interests. In other words, Ivan's love affair is NOT a case of "opposites attract" (which I always find a bit unbelievable) but rather a case of "Oh, hey, we share definitely compatible views on life and life-goals." This is not the frankly unlikely plot of a romance novel, folks, despite it playing with romance novel tropes. It is, really, a pretty calm and realistic story of two people falling in love.
Because it's part of the Vorkosiverse, though, the manner in which Ivan and Tej meet, and various other events in their courtship/marriage, are pretty spectacular, ranging from an ImpSec sting (and hooray! Byerly Vorrutyer being snarky!) to ImpSec screwing up (Byerly again, as well as various other ImpSec "weasels") and Ivan stepping in to prevent ImpSec from making a complete hash of his quiet life. Again. There are also Jacksonians, bounty hunters (mostly, as Ivan calls them, "bargain ninjas" who suck at their jobs), a pretty exciting treasure hunt and, in what is perhaps a disaster that might just top Miles's Epic Failed Dinner Party, the hilarious Sinking of the ImpSec HQ building. More excitement than Ivan likes, but nothing approaching Miles Vorkosigan-levels of excitement--fortunately for Ivan's state of mind. Overall, it's a farce much like Civil Campaign: no empire-threatening plots, and no real casualties other than people's pride or expectations. (Simon Illyan's pride being one of the most notable--the man finally gets bored enough to screw up, and Gregor is forced to quietly suggest to Lady Alys that she take him on a long vacation. Off planet.)
What I loved best about this book was the fact that, at long last, we get to meet the "real" Ivan Vorpatril. And no, he is not a superhero commando. He is, more or less, exactly what he's been trying to tell his relatives he is all along: a highly capable Ops clerk who really loves flowcharts, organization, and QUIET. What he is NOT, however, is a feckless idiot, having outgrown that years ago. Alliance points out, much to my personal delight, that just because he lacks the flashy, explosive brilliance of his cousin Miles (or, indeed, his Uncle Aral) this does not mean he is in any way stupid or incapable. He even actively sabotages a superior's glowing report of his incredibly adept skills as organizer, expediter, and general efficiency-guru because he likes his current position and does not want to risk getting reassigned or promoted somewhere less peaceful. And, over and above all of this, Ivan Vorpatril (despite being a jerk as a very young man) is a nice man. He's thoughtful, and helpful, and courteous to women. His so-successful seduction technique? Making women laugh. And also playing the odds, and going to places where there are likely many women looking for company and therefore increasing his odds of success. When he is forced to focus on one woman solely (his attempt to "rescue" Tej at the start of it all), he actually crashes and burns fairly spectacularly. Also, as he points out to Byerly, his reputation as a "womanizer" has come at the cost of many, many breakups--all of which, he also admits to himself, he has felt fairly keenly, regardless whether or not he was the one doing the breaking up, or being broken up with. Because, after all, Ivan Vorpatril is not actually a rake (this being another trope the book plays with and turns on its head): he's a Nice Guy.
And let's face it: any woman with sense--especially one who also wants a quiet life--goes after a Nice Guy.
