I've got a little over 200 pages left. I'm thoroughly enjoying it. I had bought "Brimstone" about 3 months ago and was having trouble getting into it. It's 2 books after this one in the series, so I'm glad I picked this up because it introduced the character (he actually was introduced in Relic and was in Reliquery, but he is just a minor character in those two, not the main protagonist, so I'm not worried right now about reading those two), so now when I get to Brimstone, I'll be able to get into it with no problem (as soon as I finish this book, I'm going to pick up the next one). I just recently found this series of books and am looking forward to reading the rest of them.
