A captive, wrathful Siren.

A cursed ex-pirate drowning in agony.

An artifact that could mean salvation for both if they can survive a journey to Hell-and each other.

Vengeful Siren Zephra would give away hundreds of her bewitching kisses-and probably a few stab wounds-if it meant escaping human captivity for her ocean home. After six years trapped behind glass walls in a curiosity lounge, she sends out a cryptic call for help, offering the location of a lost Siren artifact in exchange for freedom. But a lead on the Voidtome, an artifact capable of tearing cataclysmic holes in reality, doesn't draw in heroes. It attracts the attention of Reiven-a cursed ex-pirate with a dangerous amount of snarky charm and a history of hunting Sirens. When Reiven's enemies attempt to ensnare Zephra in a magical bind, he intervenes...unintentionally tethering her to himself.

Now magically chained together, Zephra and Reiven form a reluctant partnership to retrieve the Voidtome. While Reiven insists he wants to return the stolen artifact to the Sirens in the name of peace, Zephra plots to use it to annihilate the human country that ripped her from her home. Their alliance is tenuous. The attraction, infuriating. And the Voidtome's location-Hell itself-is just the start of their problems. When the pirate captain who once betrayed her resurfaces to claim both her and the Voidtome, Zephra must rely on her new ally as she faces her old trauma. And beneath Reiven's cocky front and countless secrets, Zephra finds someone almost as broken as she is.

Falling for Reiven was never part of the plan. And daring to trust a cursed Siren-hunter may shatter Zephra's fantasy of vengeance-and her hopes of returning home.
