Not Quite a Lady. The Boston Heiresses, #3

An impoverished lady determined to regain financial independence. Lady Sarah Smith-Jones had everything a young lady brought up as one of Boston's elite could expect. Until her father gambled away the family fortune and took his own life, leaving Sarah owing an impossibly large debt to a man known only as the Raven. Blackmailed into helping the Raven, Sarah cannot refuse. Recover a stolen necklace and cancel her father's debt - one job and she can return to her quiet new life as a dress designer, away from the enigmatic Raven.
The illegitimate son who built his fortune from the streets. Tamworth Arbusson is no lord, despite being the son of a duke. His fortune is built on a string of gentlemen's clubs renowned for their discretion - and their ruthlessness dealing with unpaid debts. But Tam has a secret. Should it be known that he has loved Sarah from the moment he first laid eyes on her, the designer's reputation within Boston society would be devastated and her character destroyed.
Now though, she is indebted to him - and he intends to use that to his advantage, if only to spend precious time with her before he has to return to Boston's dark underbelly. When Sarah is dragged into his world, Tam must move heaven and earth to protect her, as the stakes rise from a simple theft to deadly danger. Together, Tam and Sarah must navigate a merciless world in a race to save lives as well as their hearts.
