Welcome to the Playpen, our space for ferrety banter and whimsical snippets of things that aren't quite long enough for articles (although they might be) but that caught your eye anyway.
@Arthur: I'd buy that premise. Not quite sure what you could do with gunpowder if you didn't have a good understanding of metalworking, though. I'm thinking rockets. Lots and lots of rockets.
Also, this discussion if reminding me of a short story Paul Melko wrote called "The Teosinte War" which involved a academic trying to figure out how to put the Americas and Europe on an equal footing by 1500 by generating actual parallel Earths and teleporting in seed stocks, horses, what have you. It was a "man must not play god" fable, so everything ended in tears, with the final Earth being an initial success, only for tragedy to strike when the disease banks of both sides are exchanged and drive the entire species to the brink of extinction. There was also a cute pocket Earth whose Americas were initially developing in a promising direction, only for the Jin Dynasty to get interested. By around 1400, all of the Americas ended up as a tributary of China, and there was a long-term project to convert most of South America into farmland by slash-and-burning the entire Amazon rainforest. Even for the society that built the Great Wall, that's pretty damn impressive.
That could work. They hold off the Europeans long enough to recover from all the plagues, now with better immunity, so even of the Europeans start trying to invent heir own firearms (and it might take a while to work out all the kinks), they'll still be fighting on more equal terms.
Plus once they suss out the connection between those plagues breaking out and the arrival of European ships the Aztecs are going to be researching long-range cannon to sink any of those damn plague ships before they make landfall...
On the magic front, I recently read Kate Elliott's Cold Magic and Cold Fire, which have some similar features to this book but took them in a different direction. There are both cold mages and fire mages; Europe is dominated by cold mages (being, um, cold, especially since the ice age is lasting a lot longer there than in our world), and they find when they get to the alt-Caribbean that cold magic is weaker as you get further away from the poles and the American fire mages can kick their asses. The reliance on cold magic has also acted as an alternate technology in Europe, plus the cold mages are opposed to fire-based technologies because they threaten the mage houses' dominance, so guns are still new-fangled in the 19th century, iirc illegal, and anyway they fail if a cold mage looks at them funny. So technologically, they're on a more equal footing. Also, the Taino at least have also figured out how to use fire magic to kill the teeny little creatures which cause disease (handy when those pesky Europeans bring a zombie plague over with them), which further evens the playing field. This world also introduces a second sentient species indigenous to the Americas (who are dinosaurs! with feathers! and law firms!), but they aren't the factor which keeps the Europeans at bey (they're just there to be Way Cool, I think). The human fire mages do that. So, magic makes the difference, without making it a special mystical woo thing only for people In Touch With The Earth or however else you want to phrase the usual excuse.
Hmm. ISTR that South America has an abundant source of the chemicals you need to make gunpowder. Proposal for alt history: South American cultures discover gunpowder fairly early on, Genghis Khan dies earlier than he did in our history, limiting the extent of the Mongol conquests to such an extent that the Mongol invasion of Europe - which went a long way to drawing Europeans' attention to gunpowder as a weapon of war - didn't happen.
End result: Spanish arrive and are blown out of the water by the Aztecs, who have superior dakka.
Slower (and different) does seem to be the key (as opposed to "impossible") since, as you point out, they did get some fairly complex civilizations going in the Americas. The conquistadors were impressed by Tenochtitlan, eg. (No sewage flooding the streets, imagine!) Plus, adapting crops north/south is harder, but they did get corn all the way up to New England - it just takes a while.
But introducing a magical/alien species and slapping a name from the sagas on them just seems out of left field. Why not have a few fishing boats from Europe blow waaaay off course, bringing smallpox and influenza with them (say the boat has the last two sick survivors of the original crew, whatever), about a thousand years early, giving more time to build up resistances to at least a couple of the big diseases? Or if you're going to bring magic into it, why can't the human inhabitants of the Americas have the awesome magic? It's like the author is saying the indigenous inhabitants just weren't going to be able to protect themselves any better, not even with magic pharmacology awakening special powers, like it's some kind of preordained doom totally separate from circumstances. (Seriously, there is no way to imagine a magic pharmacology which could provide some protection against new diseases? Or at least invent a European-specific bioweapon to even the odds? Nothing?) No, they need magic saviors. That... sounds kind of icky.
Even though I haven't read any of Jared Diamond's work, I do have a bit of an irrational prejudice against him. No good reason for it, other than the fact that my interpretations of history tend to the anthropocentric and the metaphysical while he's solidly empirical and ecologically focused. Still, his approach is useful when dealing with periods where there are no relevant records available.
As for his theory, I could buy it, but I always felt the major factors the America were "slow" to develop was the fact that, well, they were settled later than the rest of Eurasia by fewer people, and thanks to the warming after the Ice Age and human predation, there weren't as many species around that lent themselves to widespread domestication as existed in Europe, Asia, and Africa (which is another kick in the pants for agriculture, since if humans need crops, animals need more crops). There weren't even horses in the Americas until the Europeans imported them over, and in the Old World horses are the backbone of every major preindustrial civilization. I not saying development would never have occurred; humanity is way too tenacious to not exploit any possible resource to the limit. But it would have taken longer, because the Americas would be starting long after the Old World did, and would have to make do with fewer initial resources. Development along familiar lines certainly was occurring; there were mound-building cultures clustered along the Mississippi and Ohio rivers and the Great Lakes that came and went in waves but were getting pretty centralized around the 1000-1500 AD period. And there were sophisticated societies in Peru and Mesoamerica, the latter of which was just starting to shift into the Bronze Age when colonization began. Still, if you wanted an Americas that could compete with Europe on equal technological terms, you would probably have to wait until the year 8000 or so.
As for Ms. Lyne's book, my snap judgement is that is feels a bit like premise overload (imagining an entire alternate species that uses "magic" that dwells in eastern North America is kind of a long way from the initial question of how indigenous populations could have met the colonization on an equal footing), and that in terms of sensitivity, replacing entire populations with aliens tailor-made to the requirements of the story may be the equivalent of vaulting over a pit of punji sticks, only to land on a claymore.
Now ask me about The Years of Rice and Salt!
Anyway, essentially, Diamond is trying to answer the question, why did people indigenous to the Eurasian continent militarily overwhelm people from the Americas in the C15th rather than vice versa? Why didn't boats from America arrive in Portugal loaded with Seminoles armed with guns & horses rather than the other way around? He's aiming for an explanation based on geographical and botanical principles rather than a "narrative of history" where events are caused by individual decisions - ie, it's not Columbus or Henry the Navigator, who are only proximate causes, it's the context they came from.
He covers all kinds of stuff in the book, some of which is disputed by other scholars, but the thing about N-S vs E-W axes is that in C15th Europe agriculture was much, much more productive than in the C15th Americas. And the short answer as to why is "wheat vs maize & potatoes". I found the stuff about the history of wheat extremely interesting; harvesting grasses with disproportionately large "seeds" didn't happen overnight.
Anyway, I don't have anything to say about SF&F inspired by his work, but I think it's an interesting book.
(It also implies that food is the only significant trade good, which is a whole other variety of WTF.)
TIME I NEED TIME.
Dammit, Kyra, you need to cater to MY schedule here! I need reviews! I don't care what kind "life" and "responsibilities" you have!
I liked it better than the book (but that means little, since I didn't really like the book at all).
From what I've heard, I don't think they have safewords... either because boundaries are for pussies OR because kinky urges come from a deep dark place in Cullen's psyche (because KINKY PEOPLE ARE WEIRD AND BROKEN RIGHT) so he doesn't bother with basis safety precautions.
...or because the author doesn't know the first thing about how this shit works IRL?
I understand the safety word is "Greyskull".
It's "Grayskull" ya damn Brit! Stop trying to subtly recolonize American fantasy!
Valse ... you tempt me so badly.
Dammit. I can resist anything etc.
