I’ve read most of her work. Started with the Shadow & Bone trilogy, the Six of Crows duology, and got through the first half of the King of Scars duology.
Ninth House is easily her best work. I devoured the book in a day and bought Hell Bent about 2 seconds after I finished it. The twists at the ending gave me literal goosebumps. Bardugo has outdone herself. I cannot wait to start Hell Bent.
