Covenant's End

The young thief Widdershins returns home to face her destiny in "her last and most dangerous adventure" in this series finale—a "smart fantasy with heart" (Kirkus Reviews).
After almost a year away from the grand city of Davillon, the wandering thief Widdershins has finally come to terms with the pain and grief that drove her away. Now she's returning home with the hope that her old friends can forgive her hasty actions. But home is not what it used to be.
The entire city is on edge, with rumors of upheaval spreading through the darkened streets. And Shins is shocked to discover that her dreaded nemesis, Lisette Suvagne, is behind the strife. Thanks to an unholy bargain with otherworldly powers, the vindictive Lisette is far more dangerous than before—and far too formidable even for Shins and her personal god, Olgun, to confront alone.
Now, for the sake of her friends, her city, and her own soul, Shins must gather allies from every corner of Davillon—lawful, unlawful, and seriously unlawful—before she faces the greatest challenge of her life. Because the greatest challenge of Widdershins's life might also be the end of it.
