The Mammoth Book of Alternate Histories
The idea of “what if”, especially in historical contexts, have always fascinated me. What if Hitler had been assassinated before the World War started? What if the Americans had lost their war of independence, and India won theirs? What if Islam were the major religion in Europe instead of Christianity? The book is a massive collection of such “what ifs”, and you are bound to like at least a few of the stories.
