Bought it yesterday. What do you guys think? Is it any good?
Yes I enjoyed it the first time.It isn't strictly AH but a sort of time travel story in which a different outcome occurs at a point of divergence that no one would have guessed from historical records. Effectively it supports the butterfly effect.
Try reading a Rebel in Time by Harry Harrison that tackles a similar theme only there is a minor change in outcome
...Not strictly AH? If I may remind you, the time travel only takes place in metatime after the POD. In the BtJ universe, Lee normally wins Gettysburg.
