I've long been a fan of Cold War fiction (I frequently TA a Cold War course at a local university, too). I learned about this series through Ian Tregillis's participation - I'm a huge fan of his work, and in particular the Milkweed Triptych.

A gripping, sweeping Cold War fantasy series, I really enjoyed this. All of the writers contribute excellent chapters, and I zipped through it. Definitely recommended.

I have a super weird obsession with Russian history. I don't really know why, other than Catherynne Valente's Deathless ruined me for life and now I feel like I have to read ALL THE THINGS! And The Witch...is certainly one of those Things.
Even the set up for this story is really cool to me. It's a serialized novel, meaning new stories come out regularly, from a team of writers. It's not exactly a new concept, Charles Dickens did it back in the 1800s, but it's still something different, as opposed to having to wait a year or longer (*side eyes George R. R. Martin*) for the continuation of the story.
I got the omnibus of Season One of The Witch...from NetGalley, and it's absolutely everything I love. Set in beautiful European cities? Check. Spies working for both sides? Check. Magic that isn't super easily explained in one page? Check!
I love that the story opens on a mystery, and is told from two very different perspectives of the Cold War. Everything just...converges in the middle, and it's a tense ride, but not an unpleasant one. It's like riding a super winding road, but you've had just the right amount of ginger candies, snaps, and ale to make you not want to die. I personally can't wait to start reading Season Two!
I give The Witch Who Came In From the Cold five elementals out of five!
