This may be a rushed review, but there wouldn't have been that much to say either way. Hammers in the Wind is pretty average, or perhaps a better term would be common, in terms of writing and action and has little of note in terms of depth, worldbuilding or characters. For those reasons, coupled with the fact that it's quite short but split in a relatively large number of chapters, which in turn are usually split into sections as well, it reads pretty quickly at least.
While I did notice some spelling and grammar issues, I wasn't that bothered by them, though of course the fact that the book gave me few reasons to actually care for it may largely explain that. What did bother me, on the other hand, was the fact that events, decisions and revelations tended to just happen, without carrying the weight they should have carried, and plenty of things don't quite seem to follow. That's usually a matter of how it all feels, perhaps in large part due to that lack of impact I mentioned, the issues not being easy to quickly verify, but a few obvious continuity errors that struck me were how Boen was close to 50 in the inn but 60 on the ship, how in the last chapter Maleela was surprised by a certain character's identity despite quite clearly knowing who he was and what he had done both before and immediately after, or even how the next book in the series is titled Wrath of a Mad King at the start of the excerpt but, correctly, Tides of Blood and Steel at the end of it.
