Honestly, it was a toss up between the Golem's Eye and the Ring of Solomon for me.
I ended up going with the Golem's Eye because I desperately love Kitty Jones, and that was definitely "her" book. Also, the fact that Queezle is in there is always a plus. The only reason I hesitated is because I like Faquarl, and he's more in the Ring of Solomon, which I enjoyed for other various reasons.
