What Stalks the Deep is the third in T. Kingfisher’s “sworn soldier” series featuring Alex Easton. I highly recommend all three and they do relate to each other, but each of Alex’s adventures is complete in itself, so you don’t absolutely have to read the first two to enjoy this one. All you need to know going in is that Alex has been invited to America to help a friend, Doctor Denton, who was instrumental in defeating the mysterious evil Alex encountered in the first book. The way the invitation is worded, Alex is pretty sure Denton has encountered some new mysterious evil and Alex is not one to abandon a friend or shy away from battle. So off to America it is!

If you haven’t read any of these, “sworn soldier” is pretty much its own gender identity in Alex’s home country of Gallacia. Alex was born female but took on this new identity and pronouns (ka and kan) when ka became a career soldier. In Europe, this is generally accepted as “one of those quirky Gallacian things” and people are curious but not alarmed about it. Fellow soldiers tend to recognize one of their own breed in Alex. Americans, of course, know jack-all about this tiny European country so mostly Alex just poses as a man instead of trying to explain Gallacian language and culture. None of this is vital to any of the stories, I just find the whole thing (and Alex’s wry comments on Gallacia) interesting and amusing. I also think it’s a cool way to present the unique life experience and bond soldiers often have. Gender aside, it is its own thing, you know?
The real meat of this story is that Denton’s cousin has disappeared while exploring an abandoned mine his family owns, and there’s reason to think strange things are afoot. Finding out requires exploring the mine itself, and in the process Alex has to constantly remind themself (kanself? Kaself? I don’t speak Gallacian) that ka is a badass soldier who is absolutely not claustrophobic or scared of being deep underground. Nope. Nosiree, Alex isn’t scared one little bit and ka’ll die before ka’ll say otherwise. I love Alex.
As they explore the mine and nearby town, the friends do indeed find something mysterious and maybe evil. I don’t want to give anything away, but the “sworn soldier” series (and a lot of Kingfisher’s weird tales) generally lives in that muddy area between natural and supernatural and this book definitely lives in that area. Kingfisher takes a lot of inspiration from classic authors of weird tales, like Edgar Allan Poe and Arthur Machen, and this particular one draws inspiration from Lovecraft and his stories of ancient gods and buried mysteries. I enjoyed, as I usually do, the updated and creative spin she put on the classic theme.
I haven’t reviewed a Kingfisher book for you yet so you couldn’t possibly know this, but I love her work. I can always count on her for engaging characters and solid storytelling, and though she leans more toward haunting and fairytales than gore, she’s great at creating a spooky atmosphere and has a real knack for creative and disturbing imagery. I haven’t read a book of hers yet that I didn’t enjoy, and I find Alex Easton’s adventures especially delightful. Plus the cover art is awesome. I listened to the first two books on audio* but someday I’ll have to go buy physical copies because the artwork is just that good.
*I don’t listen to a lot of audiobooks but I recommend these if you’re into that sort of thing. All the books are written in first person as if Alex is telling us the story, and Avi Roque does a great job conveying Alex’s sense of humor and soldierly stoicism while preserving ka’s unique identity.
Until next time . . . as always, embrace the darkness and read more books.
