Emma Ryland meets her enigmatic hitman, Silas, in the rain-slicked darkness to seal their deal with a vial of her own blood. He accepts her visceral payment but warns her the true cost is far greater than she imagined. Their transaction forges a terrifying and intimate bond, pulling Emma into his shadowy world and binding her to him with terms she does not yet fully understand. The price is her silence, her loyalty, and perhaps more.
