Hell Hath No Fury by Rachel Aaron

The Queen of Wrath may go down, but she’s never out. At least, that’s how it’s been for the last five thousand years. With the loss of her horns, hand, sword, name, and witch, Bex is closer to defeat than she’s ever been before, but the Blade of Ishtar has never been a quitter. She’s determined to come back from her ashes, which means it’s time to do something crazy, something she’s never attempted in any of her previous lives.

She’s going to hell. Literally.

If the only way to get back what she lost is for Bex and crew to personally storm the Eternal King’s prison, that’s what they’re going to do, because while the Hells were designed to contain demons, they’re completely unprepared for the fire of revolution Bex is bringing with her, especially since the demons aren’t fighting alone. Adrian is also deep in Heaven’s backstage, and like any good witch, he hasn’t been an idle prisoner. It’s time to show Gilgamesh that winning the battle isn’t the same as winning the war, and that hell hath no fury like a queen–or a witch–scorned.
