A year ago, I was fairly sure that 1637: The Transylvanian Decision was going to mark the end of the road for the Ring of Fire series. Eric Flint was dead, his widow had been forced to declare bankruptcy and had shut down the Grantville Gazette e-zine, and the entire catalog of Ring of Fire Press ebooks had been pulled off the market. Well, things are looking up for the 'ol Ring of Fire. A new incarnation of the e-zine is back, at least some of the RoF ebooks are available again, and here we have a new release in the series (though, admittedly, not in the main series, a continuation of Gorg Huff and Paula Goodlett's Russian Civil War side-series). It's a solid addition to the story, and seems to wrap up a lot of the Russian storylines up to this point (I'm not going to sum-up, it's too complicated) and moving towards Russia becoming involved in affairs in East/Central Europe and in China. I must say that I feel the co-authors have substantially improved in their writing over the last decade and while their first couple books in the franchise were "ok" as holdovers between main series releases, this was a fun book. My only real problem with the book is that it's packed with a bit too much plot for its length and (especially near the end) it rushes through some major events without taking the time to properly build them up or embrace the dramatic potential. It's not dry by any means, the writing is funny, and the characters are endearing, but there's so much here that I feel like it would've been better as a 450-500 page book, rather than the 330 pages we got. Also, slight stylistic critique: there's no map. I think I have a fairly good idea of the basic shape of Russia and its geography, but between the fact that the places in the book have different names than their modern-day equivalents and the fact that the events of the story universe have altered the political geography substantially, a map of 1637-1638 Russia and environs would've been a good addition. Plus, I love books with maps in them. Oh, one other thing, I haven't actually read the "Miroslava Holmes" ebooks by the two authors, which are detective mysteries set in the Ring of Fire universe in Russia, but several characters from those stories show up in this book (and references are made to events from those stories), so I'd suggest reading those first, though they aren't necessary for previous novels in the Russian series. I have to say, this book really whetted my appetite for a new mainline entry, so many things were left hanging at the end of 1637: the Polish Maelstrom, and I'd love to see what happens next even without Eric at the helm.
