Harry Turtledove Strikes again
Having enthused about his "world war" series I lifted another volume off the shelf at my local Library this week.
"A World of Difference" gives us the Mars we always wanted, a bigger warmer planet with oceans, water icecaps, and seasons, huge canyons with raging seasonal floods, Intelligent life with its own agendas and chemistry and a wonderful twist of history with the Viking 1 Lander attacked by a spear-wielding native.
There's more, but I don't want to spoil it.
I can't find it at Amazon, but put it on your wish lists...
