Oh I loved Pact, my favorite magic system/world building for an Urban fantasy. I even attempted a reread on it, though on the 2nd time I don't think I got much farther than Toronto. Will definitely get to Pale once I finish Ward. Twig didn't do it for me, but it was also the first WB book I read as it was coming out. I prefer to read them when they're all finished personally. I fell off track with Ward several times.
