Apparently November will see the release of the first in a series of books covering the Italian Wars. The first one covers the Charles VIII period.
There are also a number of other interesting books pending, including, amongst others, more offerings in the series covering the 1720 -1815 period, the later C16th, the Thirty Years War, the Wars of Louis XIV, WWI and WWII.
Helion also have a free downloadable magazine on their website. As well as information about new and forthcoming titles it also includes articles written by well known historians and wargamers. Issue 6 is a wargaming special with figure painting tips and a couple of WSS scenarios. Pretty good stuff for a freebie.
