I feel really uncertain what I want to say about this book. On the one hand, there's a great deal that delighted me about it. I never felt sure where the story was going to end up, which I love. It was interesting, character-wise and in world-building and if Tanzer makes it a series--as I hope she will--I'm definitely on-board.
But, for as much as I enjoyed the book, it falls short of being completely satisfying, so I liked it a lot, but I don't love it. If pressed to a number, it's a 3.5.
There's a lot that's really interesting about Vermillion. Lou, our heroine, is a genderqueer, half-Chinese psychopomp. That is, she lays the unrestful dead, whether they want to go or not. Lou struggles--with her gender, her racial identities, with her past, with her future.
Lou's also not the only interesting character. We have sentient, talking bears and sea lions, responsible for massive changes in the history of America and Western expansion. We have the mysterious Dr. Panacea and his right-hand, the equally enigmatic Shai. The love of Lou's past, Bo Wong and his band of monster-hunters and the delightful, irrepressible Coriander. It's a great cast of characters and there's a a broad range of sexual and gender expression to go with it.
But I think that, in the end, I like the ideas and the possibilities of the story better than I like the actual execution. Lou is an interesting protagonist, but she's often not smart and she bumbles her way through the investigation and, while that is a COMPLETELY VALID writing choice, I really prefer stories about smart, competent protagonists. I also feel like, although Lou feels like a fairly complete person, most of the other characters do not feel as full or textured. I spent a lot of the book not feeling sure how I was supposed to take the characters, because on the one hand, there was a certain amount of face value information given...but at the same time, the trappings of the story are those of a murder mystery and surely I wasn't supposed to take so much at face value? Except at the end of it all, I'm pretty sure I was. Which is just less real and less fun (for me).
And then there's Shai. Shai and his relationships with Lou and Lazarus are, in my opinion, the most interesting parts of the book. To use a fandom term, the three of them are weird about each other in really interesting ways, ways I wanted the book to dig into more deeply than it did. But Shai feels weirdly incomplete or maybe fractured as a character. The Shai we see with Lou in the trek to Estes Park and the sanitarium feels VERY different than the Shai we meet later on, and I don't feel like there was enough groundwork to satisfyingly marry those two different presentations. It felt like something big and important was missing from the narrative to explain how Shai could be so different, from part A to part B.
As well, the world building felt like it needed a little more padding. The idea of sentient bears and sea lions, and their subsequent effect on the history of the time, is fun and cool, but it didn't ever quite ground itself or create a strong foundation for the rest of the story to spring from. To compare and contrast, Seanan McGuire's Incryptid series posits a number of supernatural creatures living alongside and barely out of sight of the regular population. Gorgons have jobs at zoos and strip clubs. A dragon lives under NYC. But it's all grounded in a certain 'realism' (for a given value) that colors the entire world. Whereas this felt more like George RR Martin, in that so much of the world is mundanely ordinary that I never know HOW seriously to take it when magic or the supernatural is presented or how far it can be extended. Okay, Lou is a psychopomp, she handles the restless dead...but that doesn't mean that vampires or dragons or werewolves are a natural extension of that world. I don't know what the rules of Tanzer's world are and she doesn't give any real warm up to the pitch. It's just "here you go!" It doesn't feel complete, it doesn't have the heft of something I can entirely buy as 'real'.
So it's good, but I want it to be BETTER. That being said, I do feel it's entirely worth reading and, as I said, if Tanzer goes on with Lou's adventures, I'm in for the long haul.
