Query: Actually, I only wanted to give it zero stars

Ok, the first book, Red Mars, was a slog but at least it was new, very well written with lots of mind-numbing detail. Repeat that for another 624 pages and it starts to get very... heavy... going... In fact, this has become the definitive "I'll just read this other novel and then I'll get back to it" novel - and its not a 3 book burner, its getting way up there in the double digits now. Toooo ssssllllloooowwwww and heeeaaavvvvvvyyyyyy to progress with no enjoyability factor
