Ninth House
Bardugo has a special talent in scaring the shit out of me and finding new ways to horrify me by her books. Ninth House contains all the ingredients for a perfect Bardugo thriller; it's dark, gritty, bold, and honest; not shying away from the ugliness of life.
A brutal, fast paced, full of magic novel, that will keep you hooked from page 1.
The character and world building is amazingly done. I really connected with our main heroine, Galaxy 'Alex' Stern, she was a morally gray character (Leigh Bardugo excels at writing such antiheroes and tragic villains).
