The prospect of a Cold War era spy thriller in the fantasy genre excited me, when I first learned about this book, and indeed the premise remains one of the strongest aspects of the book. In Prague, secret agencies of all types wrest for knowledge and power; CIA, MI-6, The KGB--but there are two others operating even beyond the knowledge of the usual organizations, Ice and Flame, cabals of witches who have infiltrated other agencies and are working towards higher stakes--it's not just about the political landscape, it's about the fate of the world itself.
There are a number of characters in this book, but the circle is kept relatively tight--though we follow a fairly large cast of perspective characters, they are generally the only characters in the book, aside from a few extras. It helps keep the story from spilling over itself. Primarily, we follow Gabe Pritchard, an all-American CIA operative who, at some point in his past, had a little run in with something he can't explain, and now there's a hitchhiker in his head trying to get out, and it's affecting his work. On the KGB side, we have Tanya, who is also a witch for the Ice, attempting to extract a young woman of interest to the Ice before the Flame can get her. Invariably, Gabe and Tanya's paths cross, and much of the tension of the book comes from them having to work together for the interests of Ice, while being enemies in their other agencies. This second layer of intrigue adds a nice twist on the usual spy story, in fact--it's not just about who might be an operative for another organization, but who might be a witch working against you.
The characters themselves are fairly strong, due to all of them getting some time to carry the story. There are diverse personalities playing off of each other, but there isn't generally anyone who comes across as incredibly unlikable or annoying, at least for me (although Josh, Gabe's partner in the CIA, gets pretty frustrating).
The book is also episodic, which was one of the most talked about features when I was looking into this book; some people hated it, while other people loved it. I have never read a serial novel before, so I wasn't sure what to expect. If anything, I was surprised by how normal the book read. I don't read closely enough, I suppose, to really notice and be thrown by different authors writing certain episodes. To me, it just felt like one continuous tale, just like any other novel--perhaps with a few filler episodes thrown in.
That said, the plot is largely the biggest knock against the book for me. By around the end of the book, when the characters are preparing for the ending, I got bored and started glancing over paragraphs until I got to something interesting. The problem is pacing. The story never really builds to anything. Yes, there's an event in the last episode that feels like a "finale" but it's just so underwhelming that it didn't really work for me as a drawing together of the characters and conflicts of the books. It felt more like the authors knew they needed a set piece to finish off on, and delivered, but there was little heart or anticipation to it. The best climaxes are the ones that force characters to overcome their differences, their prejudices, their obstacles, while tying up loose story threads and culminating in an emotional and physical pay-off. I could analyze why I don't think this book's climax accomplishes any of that, but to do so would require spending a lot more time talking about specific scenes and revelations.
So I will just say that the climax doesn't really do much for tying up loose threads--it DOES feel like a logical continuation of the story at that point, but there are obviously a lot of relationships and subplots at play here--in a book where we get scenes from just about everyone's perspective, and everyone has at least three secrets stuck tightly to their chest--and nothing really gets wrapped up here. It feels like the characters end the novel in much the same place as they started, albeit with certain new information that they didn't have before (and which didn't come about from the climax). It's an annoying return to the status quo, and the climactic event feels relatively detached from the story itself. And then the book just... ends. I assume there are more stories beyond this, that they've always intended for a "Season 2" but it's a bad television show that doesn't resolve many of the threads and conflicts by the end of Season 1 while hoping new, interesting conflicts will hook a viewer into Season 2.
I also blame the stakes of the novel, which more or less stay the same all the way throughout. We get a very early distinction between the Ice and Flame, that the former wants to preserve the world while the other wants to tear it apart. While this binary is probably too simple (we learn things about Ice, and we get some perspectives from Flame witches) it also more or less informs the stakes of the novel: if the Flame get what they want, they'll destroy the world. For some reason. Somehow. There are some moments of really good, personal stakes, but they almost always tie back into the Flame being victorious, and this looming threat of the Flame destroying the world. It was hard for me to be invested in such a vague threat, especially when the subversions of the book taught me that it wasn't probably so simple. So when the final threat of the novel more or less is "if we don't stop this thing from happening, it brings the Flame one step closer to destroying the world," I was just bored.
Much of the novel's conflict also revolves around the question of "will they work together?" in regards to Gabe and Tanya overcoming their mundane political animosity for the good of Ice. It's a good question to throw out once or twice, to make us really doubt things are going to go well, but this book asks that question far too many times, and never really changes its answer, so it loses its weight--especially when it's still asking that question in the last two episodes of the book.
Finally, and this is perhaps the most dependent on my personal preference, but I cannot stand when a multiple-perspective story, just before a big event or revelation, switches to the perspective of someone who is either not present at that event, or does not have the information to understand the revelation. There are quite a few scenes where a character will be about to unearth some secret, or will be pulling off an operation they've been building to for a few episodes, only for the narration to cut to another character who, at best, only gets to see the residual effects of that revelation or event. In some cases, we don't return to the original character for some time, and by then the character is living another day and isn't even thinking about what they've uncovered, so that the writers can reveal it later, from another character's perspective. It felt cheap to me, and annoying.
I had high hopes for this book, and I really did want to like it, going into it. A strong opening drew me in, and the cast of characters was intriguing and varied enough to keep me interested. But the book was average to me, without any sense of rising stakes or tension, capped off by an ending that felt obligatory and didn't really do anything for me. It's hard to make justifications for a book when I'm skipping pages in the last twenty, ready to finish and move on to something else.
