In the explosive third book of the viral Heavenly Bodies series, Elara and Lorenzo have no choice but to join forces with their greatest enemy to stop the Dark from destroying the world, but as their power grows and their bond deepens, love itself may become the price of salvation.

The Dark has returned--and she's hungry for hearts.

Whispers of war echo across the realms. If the Dark collects the hearts of all her Stars, she'll raise an army powerful enough to destroy gods and mortals alike. To stop her, Elara must do the unthinkable: ally herself with her greatest enemy, the ruthless King of Stars.

In the brutal ice kingdom of Perses, where violence is honour and mercy is weakness, Elara and Lorenzo are bound together by a fragile alliance--and a dangerous desire that threatens to consume them both. As her immortal magic grows, so does her lust for vengeance, blurring the line between salvation and ruin.

To save the world, Elara may have to surrender her heart--and become the very monster she swore to destroy.
