(just a note: I'm reviewing the series as a whole, because these books aren't good enough to warrant individual reviews. Sorry if that sounds mean, but I had to read these, and you didn't, so there.)
I get that basing a series of novels on a role-playing game can be fun (especially one where players take on conspiracy theories and shady bureaucratic rabbit-holes), and to be fair, I was really into these when I'd first read them. The problem was, I'd started with books 2 & 3 (those were the only ones I'd found at the time), which is not the way to start a sequential series, no matter what The Teenager's mother might tell you (you can't start on a tv series at season 4, IT DOESN'T WORK THAT WAY), so since then I've been idly wondering how the whole thing started, and how it ended.
Two decades later, I came across the rest of the books in the series, and decided to revisit the whole thing. I'm not sure that was the best idea. I mean, I'm down for an X-Files homage as much as the next person, but these are not good. This isn't even second-rate, this is what second-raters look down their noses at. There's no character development, just trope-y descriptors passed between authors: Fitz is a secret clone of JFK, a fact that never really gets explored; every book just takes great pains to mention that he's a 'natural leader of men', and other than a having a penchant for making truly unfunny witticisms, that's about it. His partner is DEFINITELY NOT Dana Scully, despite the red hair and skepticism - and of course, large heaving breasts. The malevolent force they're investigating (the Dark Tide), is never really fully explored/explained, just a catch-all classification given to anything paranormal or supernatural. Aliens? Dark Tide. Nazi's infiltrating the government? Dark Tide. Holy Grail hunters? Dark Tide. Chaos magick, yetis, ghosts, state buildings hiding vast subterranean tunnels leading god-knows-where? "The Dark Tide is rising!" They even have a wise Tibetan supervisor who either speaks in cryptic riddles or vague platitudes, and is often mystified by our strange western ways. There's never any real resolution to anything they investigate, just shootouts, exploding buildings, and shrugs. I'm just, man, ugh. So disappointed.
(In all fairness: I didn't actually read the fifth and final book, so maybe everything did get wrapped up to everyone's satisfaction. But life's too short to risk wading through this kinda garbage to find out.)
I gotta say: younger me has a lot to answer for. The only good thing about this series is that it gave me something to read on the toilet. 2/10 would not eat here agin, because some weirdo in a fedora would probably interrupt my meal to whisper 'the Dark Tide is rising' before running away with my cutlery.
