I'm really enjoying it so far. There are a few clunky bits but it doesn't detract too much. Perhaps if it becomes more popular you could rewrite the beginning and/or designate another chapter as a starting point?

Ch2-7: * ruminating on the downsides of being a female cow would seem to be a good lesson in empathy for human females, but the point seems to be lost on her. * the Queen gives in quite quickly. Even in Equestria, surely there are many scammers and leeches and deluded people that a simple Pascal's wager wouldn't work. * Stealing from MoR? really? Most of the passage too?! Again, jumping to those specific bits are not what a non-LWer rationalist would do; instead, they'd point out something about perpetual motion or bombs. Don't bring up time travel unless your character can actually say clearly how it would lead to time travel! (Grr, it's not deducing if the character can't even explain it, as I bet you can't.) I note with disapproval the blatant theft in chapter 13 as well. * Would the character really expect the queen to know a word like 'sapience'? I expect even most LWers would get it wrong and confuse it with 'sentience'. * Hilarious udder joke. But I'm surprised any cow would be that flexible... * 'consultat' * 'Luna looked pained, and looked away from us both, which was answer enough', isn't this obviously an answer to her previous question about where she is in the timeline? * 'the deliberate act of some powerful being' and where did this all of a sudden come from? Did perhaps the queens just listen to her story and were all like 'oh yeah, I know what explains this, a powerful magical being!' and she wasn't all 'that's stupid and as bad an explanation as "magic" on a blank map'? * Enjoyed the rhyming, although I have no idea what that was all about. Ch15: * "... I ripped the tag off of a mattress. How about you?" You know that it's perfectly legal for the end-consumer to do that, right? Or is that the joke? Not sure if I'm interested enough to keep reading, but at least it's not a terrible fic.
