This one is an episode, very much in the TV sense. A major plot event goes by, but in a self-contained sort of way. Some major characters meet up, so those plot threads advance. The big bad guy is temporarily foiled but gains a huge advantage. The good guys gain a small one. Okay, I could be describing any mid-late volume of a series, but Fatal Error felt a little thin. It's fattened up by a couple of horrible people being horrible in a completely human way, and then Jack beats them to a pulp. Effective but artificial tension. I'm not saying the series shouldn't go there -- its heft lies in addressing racism, bigotry, and selfishness in the same breath as demons of the apocalypse -- but the author seems to want to push all the elements over-the-top at the same rate, and he winds up just turning some chapters into a gorefest.
