A stroke of the pen and history is changed. In 1938, British prime minister Neville Chamberlain, determined to avoid war at any cost, signed the Munich Accord, ceding part of Czechoslovakia to Hitler. But the following spring, Hitler snatched the rest of that country and pushed beyond its borders. World War II had begun, and England, after a fatal act of appeasement, was fighting a war for which it was not prepared. Now, in this thrilling, provocative, and fascinating alternate history by Harry Turtledove, another scenario is played out: What if Chamberlain had not signed the accord? What if Hitler had acted rashly, before his army was ready---would such impatience have helped him or doomed him faster? Here is an action-packed, blow-by-blow chronicle of the war that might have been---and the repercussions that might have echoed through history---had Hitler reached too far, too soon, and too fast.
