Resisting my enemies might prove harder than I thought. Atlantic City is awash with dirty money. The Prohibition has made some good men smug and many bad men rich. I, Rose Greenwood, steer clear of both. I have been dealing with other sorts of spirits: pretending to speak with ghosts on behalf of moneyed widows. Then a fake seance gone wrong had landed me in the clutches of a police inspector who gave me a choice: a prison for fraud or a secret mission on his behalf. It seems I am to act as a spy in the ranks of Northside Sinners: the most ambitious gang in town, ruled by three notorious brothers. Kieran, the cold-eyed leader, the master of schemes. Declan, the scarred soldier who is a bit too handy with the knife. Colin, the boyish, eager enforcer with a taste for high life. To escape the trap, I must betray them - but what if my heart betrays me first?
