I'm not to sure if this is the correct place to post this on but as this is the only forum I lurk on I thought I would give it a go. I'm looking for two books I read a couple of years ago, they are more alternative history than fantasy but as I like both there may be someone here who has read both. They are two books in the same series about the first walled city in Europe, which is attacked by a tribe of horsemen and defended by the town guard of bowmen. The first books not very long, the second is significantly longer. Any help tracking these down would be massively appreciated.
