A fun and often cathartic exploration of time travel surrounding the most significant What-If of modern history. It doesn’t take itself too seriously (a fault of many time travel stories), though sees to the subject matter with appropriate solemnity. I’m not one for crying, and this book is no exception. Still it did, including the afterword from the author, touch me. The book is a long haul, but it is prescient and thought-provoking.
