Last time I read it I gave up around half-way. I really like the beginning but it drags for me in the second half.I've a feeling that's going to be the case for me. I wasn't really looking forward to Consider Phlebas as it was one of my less favourites first time through. But I'm loving the first third of it so far more so than I remember!
The same goes for one or two others, yet I can read Excession over and over again.
