I picked this up secondhand and have started to read it twice, but thus far I can't seem to get hooked on it. I may try again over the winter - it "feels" like a curl-up-on-the-couch kind of book. We'll see.
Nope, I give up. There are points here where I think I can see what Bear was trying to do, but it's just way too convoluted to hold my attention.
