Shattered Gods by Katee Robert

She was Olympus’s Queen. Its sacrifice. Its savior. Its destruction.
Long ago, Circe was Hermes’ entire heart. The two women lived on the outskirts of Olympian society, content with a quiet life away from the spotlight. Then Circe caught the eye of Zeus…and was forced into a marriage that would take her freedom, her future, and in the end, her life. In the wake of the tragedy, gossip swirled about the woman Zeus married and (allegedly) murdered…but in time, everyone forgot about beautiful, tragic Circe.

Everyone but Hermes, who vowed on that day to bring Olympus to its knees.
Now, fifteen years later, a new Zeus rules the city, a new Hades protects his people, a new hope dawns…and Hermes has begun to think there may be things about Olympus worth saving. With Atalanta by her side—and slowly rebuilding her heart—Hermes may finally be ready to set aside her fury and seek the city’s rebirth instead of its total annihilation. But there is a beautiful devil on Hermes’ other shoulder: a devil who rose, blood-soaked, from where Zeus left her for dead years ago. A devil who has waited all this time to have her revenge.

And no matter their past, no matter the desperate love they once shared, no matter the complicated triad forming between the three women, Circe will not rest until all of Olympus lays shattered at her feet…and the gods help anyone who gets in her way.
