I haven't read it yet, because I've got a very long list of "To Read" books that I own. I'm barely crawling through the two books that are currently works in progress as it is, what with the summer schedule and all.
However, I saw the second volume (Guards of Haven), collecting the original books four through six, for $.03 on Amazon, via a used book seller. In Like New condition. (By the way, S&H was $3.99. Total bill, $4.02. I've bought a fair number of books where the price itself was essentially nothing, but the S&H was twice or more what actual shipping would be. I suppose it's a decent way to offload catalog of used books. Shrug.) So I ordered it. I'm also going to shortlist the first Hawk and Fisher book to read immediately after I finish the Steven Erikson doorstop novel that I'm reading now.
