I read the whole thing last summer while I was recovering from a sunburn. It was pretty decent, though there was a point at which it seemed boring and drawn out. Too many characters I didn't care about when we got into troll ghosts, alternate carapacian people, etc. Also, it kind of made me mad that Jack(and a number of other old characters on and off) just sort of became irrelevant after being the absolute scourge he was earlier on. That whole drag kind of keeps me from recommending it to people. If I hadn't already been stuck at home I probably wouldn't have read the whole thing.
Despite that, the first and last story arcs, music, character design, and just general creativity keep it in a positive light for me.
