A desperate rogue. A cursed warlock. A dark pact that binds their souls and threatens to destroy them both.

The city of Arcanum is a beacon of light, but for master rogue Anya, it holds a terrible shadow. Her younger sister, Lyra, is slowly succumbing to a mysterious magical malady that no healer can cure. Desperate, Anya seeks out the one being whispered about only in shadows: Caelus, the Warlock, a fearsome ruler of a desolate, dying realm.

To save her sister, Anya makes a dangerous bargain with the myth. Caelus will use his forbidden magic to heal Lyra, but in return, Anya must help him break an ancient pact that has bound his soul for a thousand years. The pact is sealed not with a handshake, but with a magical chain of dark energy that physically and psychically tethers them together, allowing them to feel each other's every emotion and every jolt of pain.

As they journey through a forgotten world to fulfill their dark pact, Anya and Caelus uncover a shocking truth—their families are linked by a lie that echoes through a millennium, and Lyra's sickness is a direct consequence of Caelus's ancient burden. They find themselves hunted by a rival warlock who will stop at nothing to claim Caelus's power for his own.

Forced to rely on one another, their bond deepens into a fierce, unspoken desire. But as their paranormal romance unfolds, they soon discover the ultimate price of the pact: a devastating sacrifice that one of them must make. Can a desperate rogue and a cursed warlock break the chains that bind them and save the ones they love, or will their soul-binding bargain become their ruin?
