1907. New York City. A glittering world built on lies – and one murdered girl who could expose them all.

Caitlin Quinn crosses the ocean from Ballykelly with nothing but a desperate letter from her missing twin, Mary. New York is meant to hold answers – but instead it offers danger: a sprawling metropolis with a brutal underbelly of crooked deals, criminal empires and forces who’d kill to keep Mary’s truth hidden.

Then there is William Furey – a notorious gangster haunted by a rage he can’t explain. He has his own orders to find Mary, and when his search collides with Caitlin’s, their unlikely alliance sparks something fierce and undeniable.

As the walls close in, Caitlin and William realise the truth will cost them far more than they ever imagined. To uncover what happened to Mary, they must risk everything: their loyalties, their futures, and the fragile trust growing between them. Because love, like justice, exacts a price. And some sacrifices are paid in blood . . .
