Fatal Terrain is a 1997 techno-thriller novel written by Dale Brown. It is set a few weeks after the ending of Shadows of Steel. The title of the book is taken off one of Sun Tzu's passages in The Art of War: Where if one fights with intensity he will survive but if he does not fight with intensity he will perish, it is 'fatal terrain.' On fatal terrain, always engage in battle. Source: Wikipedia (en)
