Yes it is. VERY. It's a little tougher going than some other P.K.D. I've read, but it's well worth the effort.
Jazzmoose - give it another shot. For me it's taking a lot of concentration, but I'm hooked now and it's, as Lon said, amazing.
I'm reading it from THIS paperback. I was surprised to find that this is the first edition (even tho it says so on the cover - I always thought that was paperback
hype). It wasn't out in hardcover first.
