They know who she is. She knows too much.

Stella is an escort, immersed in a world of desire, betrayal and secrets. It’s exactly where she wants to be. Stella used to be someone else: respectable, loved, safe.

When a fellow call girl is murdered, Stella has a choice: forget what she’s seen, or risk everything to get justice for her friend. In her line of work, she’s never far from the edge, but pursuing the truth could take Stella past the point of no return.
