The exciting next installment in the #1 New York Times bestselling Crimson Moth series, featuring beloved characters Rune and Gideon!

Rune Winters died for Cascadia and came back changed. The resurrection left something dark coiled beneath her ribs: a growing corruption she can't explain and can't afford to reveal. Not to the political enemies demanding evaluations for all witches, and not to Gideon, the former witch hunter she married who she fears losing most of all.

As witches vanish across the country and a foreign empire arrives with an offer of protection they're too desperate to refuse, Rune is forced into increasingly dangerous choices between the woman she wants to be and the power she was born to wield.

In Kristen Ciccarelli's Dark Descent, the devastating third installment of The Crimson Moth series, some bargains cannot be unmade, and some secrets consume those who keep them.
