One Dark Window is a new adult fantasy that follows Elspeth, who lives in the mist-locked kingdom of Blunder. Elspeth has a secret—after she contracted the infection that gave her illegal magic, she accidentally let a monster called the Nightmare into her head. Now, it lives in the back of her mind and protects her.
But when Elspeth runs into a group of highwaymen, she unexpectedly ends up joining a quest to rid Blunder of its dark magic: a deck of cards called the Providence Cards.
The first topic I want to discuss is the magic system. The idea of a magical deck of cards is very unique, and I really enjoyed how it shaped the worldbuilding and the story. The cards are the only legal way to do magic; each card temporarily gives the user a magical ability.
Now for the worldbuilding. In the beginning of each chapter is a passage or two from a text called the Book of Adlers. This really helped give insight into the culture of Blunder and helped shape the world, as well.
As for the pacing, the beginning is really slow, and it takes a while for everything to be set up before Elspeth can actually go on her quest. But once the quest began, I really enjoyed being on the journey with her.
There’s a romantic subplot, as well. I’m a huge fan of a romantic subplot, and while I did enjoy it, I was hoping for a little more depth. (It’s worth noting that there’s also the fake-dating trope in this book, which I haven’t seen anyone mention!) But I’m hoping the romance doesn’t feel as surface-level in the sequel.
Speaking of sequels, the ending of One Dark Window sets up for a killer second book.
Overall, One Dark Window is a great choice if you’re looking for an atmospheric and gothic read with a unique, dark magic system.
