If you are interested in the Crusades, this is a must have in your library. This gives eyewitness accounts from the perspective from the Arab historians. This book is very readable and valuable for amateur student of the Crusades like myself. You will find yourself using this book a lot for cross referencing other books on the Crusades. The third Crusade is covered very well in this book, since it was a very important era for the Arabs during these historical times.
This book is full of first hand accounts by muslim chroniclers during the various crusades. Some of the opinions are biased and may be hateful exaggerations of the truth but I found it a fascinating read. It seemed to me the muslims wrote from a more authentic voice than that of many crusader points of view from the various books I have read. Well worth your time. Also read The Alexiad by Anna Comnena, The Crusades through arab eyes is also good. If anyone has any other historical reads worth reading please post. I really enjoy reading first hand accounts.
