Superfans doing what superfans do! (By which I mean "know too much, bordering on nearly everything," and needing an outlet for all that information, not committing murder/crime.)
This one borders, just slightly, on possibly being a bit too long - as we get introduced to multiple subplot mysteries that jigsaw in around our main plot mystery (or mysteries, I guess?), some of which seem a bit much/unnecessary beyond just showing us someone may not be guilty (the entire thing on the ship, for example) or given our main character someone else to at least vaguely trust (as much as you can trust someone when investigating multiple mysteries at once). But beyond that, it's a pretty fun romp through the attempts of a group of superfans to put together a special feature about a show that they love - and, just possibly, solve a crime (or three?) in the process (okay, fine - solving the crime is the main focus; the special feature is just a way to do that with everyone in one place, Blanc- or Poirot-style).
Our protagonist, Kit, is one of multiple superfans of an older TV show called Vixens From the Void. When one of these superfans, a seeming asshole-type podcaster or vlogger (I don't remember) is murdered during a live show (in my defense, it is right at the beginning of the story, and whenever we hear about him after that, most of the focus is on how he wasn't exactly a beacon of excellence), word comes that he might've been about to break a big story on the death (possible murder?) of one of the extras from the original series of this show. And so, to get to the bottom of this murder (and of whatever the big story was), the rest of the superfans come together to try and solve the case in the only way superfans know how: invite all the stars from that series back and film an "on-site" special feature.
After all, the murder would've had to have been committed by one of them, and maybe they'll admit it in this setting? Their flaw, of course, is not realizing that inviting a murderer back to the spot and digging up the old graves (not literally, cuz no body was ever found) has a tendency to lead to more murders.
Despite the length, and the number of mysteries that seem to keep popping up, our main cast list doesn't ever really become too broad or confusing. I mean, there are occasional side characters that pop in and out, but the mysteries generally remain within the main cast of characters - so nothing really feels like a cheap, gimmicky "gotcha!" when truths spill out. There's plenty of red herrings to keep you entertained and questioning - especially when other mysteries pop up and just confound the matter - but I do think it is possible to sort of figure out at least bits of what is going on and who is guilty (at least initially, the 'who' is much easier to figure out than the 'why'). Even the final, final reveal on the very last pages isn't completely unsurprising - it feels like a lot of movies, especially lately, have played out with this sort of twist ending (also, completely unrelated, am I missing something or is the age difference at least 20 years - which is fine, if they're okay with it, but like, I feel like it is that but it isn't ever touched on?; also, not sure it adds much to the plot, especially since "love at first sight" almost immediately turns into "fuck you, we're not talking" and just a whole lot of 'I should talk to her' followed by not talking to her).
It really does seem like a huge shout-out to the idea of superfans and nerd/geek culture and a sort-of "fan service" (a la Spider-Man: No Way Home, for example), even if many of the references are to a fake show (there are, however, references aplenty to Doctor Who, Star Trek, etc.). And I absolutely love that genre of stuff that has been coming out recently (again: Spider-Man; also, Deadpool & Wolverine), and am absolutely here for that level of fan-service. I'm not this level of superfan about any such show, but mad respect for those who are - and those who go through the effort of something like this (well, except for the ones - like on of the characters here) who totally destroy the fun or (as in at least 1 real life instance that I've read about) don't mind absolutely ruining everything if it doesn't go exactly their way.
Final thoughts: again, probably a bit long, and there's quite a few mysteries that pop up - some of which seem very 'out there'. I guess the one thing that really bugs me is the twist we get on the last pages - which seems just arbitrarily thrown in and, while definitely very twisty (and exactly the type of twist I expected to come from this plot), just further goes to make you wonder about that entire subplot of the story (not the mystery part of it; just the inclusion of that at all). However, overall this is funny and pretty fun right from go, generally keeps itself going at a decent pace, and it does wrap up all the mysteries it throws at us (even if a couple of things are maybe a bit unsettling or otherwise less than ideal). Work aside, I couldn't put this down, and the idea of extreme fan-service, even for a fictional show, is absolutely wonderful to me. It is time, after all, that the idiots in charge realize that the fandoms are real.
