I just finished "One Dark Window" by Rachel Gillig, and wow—this book is something special. The world-building is incredible, with a magic system using Providence cards that's totally unique. The setting is dark and atmospheric, pulling you right into this mysterious world, and the characters are beautifully complex. The slow-burn romance between the main characters is especially compelling.

I'm giving this book a full 5 out of 5 stars. It's the kind of fantasy that keeps you up reading late into the night, with a perfect blend of intricate plot and magical intrigue. If you're looking for a fantasy that's both immersive and original, you absolutely need to pick this one up. I only regret waiting so long to do it myself!
