As usual with an 11th volume of a series, it’s hard to not end up deep in spoiler territory. So, instead, a series of mostly unconnected thoughts.
1) It has been a long time since I’ve read one of these, so I guess I’m not surprised I couldn’t remember exactly where things had left off. What I guess is important to “know” is that the long-running arc with the (let’s say) Black Lamp Society had finally been wrapped up. Taking it a step further than that: by the end of this book, all but one dangling plot thread had been wrapped up, and only one new dangling thread had been created. It’s almost like the series is angling toward an ending of some kind?
2) The book is split into two arcs, of which the second arc is both the better and the more important. The first arc either highlights that the artist only knows how to draw one type of chick, or else it is meant to clumsily indicate that Cassie Hack is lots of different characters in lots of different dimensions, depending on how she was raised, I guess? Including an oversexed lady in even skimpier clothing who likes to take over by blowing things up and the warden of an interdimensional women’s prison, for the incarceration of the kind of oversexed lady in extremely skimpy clothing who would choose to take over by blowing things up.
3) I’m glad the next book promises to be a lot more about Vlad, what with almost everything else being wrapped up and all, because I didn’t even remember that there was something wrong with him (spoiler alert: there is), but I was very disappointed that he was sidelined almost the whole book. Though I can definitely see why it was structurally necessary to get to the end point they got to.
4) The title: I cannot find any specific thing that fits Marry, Fuck, Kill, but if I squint sideways at it, I can see where there’s sort of vaguely a game of that going on throughout the book, just barely enough so to justify someone trying to get titles moved via shock value.
 She, you’ll no doubt have forgotten by now, is the teenager on the road in fishnets and carrying a nailed-up bat with “Kiss It” burned into the non-naily portions who hunts supernatural slashers to make them be more specifically dead than they previously had been.
 Cassie’s green-skinned, monstrous companion who helps her out on the whole destroying mystical psychos task, mainly because she’s nice to him when everyone else thinks he’s one of those same kinds of monsters.
