I also spent some time sins then to proof read the chapeter "The Perpetual Crusade" or Baltic Crusades as I use to call it. Not a big contribution but it was fun to be involved and now to see the finished product.
The Kingdom of Heaven book look very nice with it´s 136 pages, hardback, full colour, 19 armylista (even more if you count the several sub-lists), 3 Historical battles and the best of all, a map of Scandinavia during the crusades;)
The only downs side to the apperance of the book are that several of the fotos of minis are very dark in colour, but that is not a reason not to buy the book if you are in to Clash of Empires rules and will game the Crusades. The armylists are in my mind very well researched and usefull, and I know that Stephens have put a lot of research in to the greate historical background for each armylist and he sholuld know as he is a scholarly in the subject.
You can find a very nice Kingdom of Heaven AAR at Stephens blog.
Here follows some sample pages from the book and ofcourse parts of the Scandinavian Crusaders:)
