First was Osprey Fortress #64: The Castles of Edward I in Wales 1277 - 1307 - now, these are CASTLES! I mean, like the sort that one would imagine...
Next was Osprey Men-at-Arms #467: North American Indian Tribes of the Great Lakes - since this is where I spent nearly twenty years of my life, and still visit regularly, I was very interested in the information presented.
