Lady A is the most notorious blackmailer in the city. With just a mask and a gown to disguise her, she sweeps into lavish balls and exclusive events collecting the most valuable currency in 1725 London-secrets.

But leading a double life isn't easy. By day Lady A is just a seventeen-year-old girl named Arista who lives in fear of her abusive master, Bones, and passes herself off as a boy to move safely through the squalor of London's slums. When Bones attempts to dispose of his pawn forever, Arista is rescued by the last person she expects: Jonathan Wild, an infamous thief who moves seamlessly between the city's criminal underworld and its most elite circles. Arista partners with Wild on her own terms in order to save enough money to buy passage out of London.

Everything changes when she meets Grae Sinclair, the son of a wealthy merchant. Grae has traveled the world, seen the exotic lands Arista has longed to escape to her whole life, and he loves Arista for who she is-not for what she can do for him. Being with Grae gives something Arista something precious that she swore off long ago: hope. He has promised to help Arista escape the life of crime that has claimed her since she was a child. But can you ever truly escape the past?
