In the late 21st century, scientists created a serum that gave every person nine lives, also known as souls. Flush with expendable life, Earth collapsed into war and anarchy, leaving the Catholic Church to step in and take control. In a world where the stealing of souls is big business, it takes people like Constance Grace, detective in the Soul Theft Division, to hunt the criminals down and strip them of their remaining souls. 

When social-climbing con man, Noah Hannock, plunks himself on the church's radar, he becomes Constance's problem. With a brand new partner, Mikon Cross and seven of her nine given souls remaining, Connie has to enter high society under a too-familiar alias to tempt Noah into her web. 

While the chemistry between Connie and Mikon is scorching hot, the reality is they don't trust each other. Each with their own secrets to protect, the hunt for Noah Hannock threatens them both. The only way they can survive is if they learn to lay themselves on the line for each other.
