Query: Intriguing Stuff from Good Historians

There are a lot of horrible alternative history books out there. In my opinion some of the worst are by the popular writer Harry Turtletub. Other than his Guns of the South, I find most of his stuff really really bad.I was very pleased to see a book of alternate history written by distinguished historians. John Keegan the Great Military History, McCollough from American Experience and Author of Truman, and Caleb Carr just to name a few.As historians, teachers, history fans, we can argue all day about some of the scenerios and what ifs found in this book. That is the fun part. Who Knows....But the bottom line is this: the book is very thought provoking. The scenerios are food for thought. The historians who are used in this collection know there stuff and can write.This is a fun book to read and even better to debate. Its time and money well spent.
