Angeline's Return (London Calling, #5)
Kat Faitour

The dangerous leader of a Russian sex-trafficking ring is on the loose in London. He’s vowed to exact a terrible vengeance on one woman for costing him his freedom and power: Angeline Sinclair.
Twenty years ago, Angeline lost everything when she made the impossible choice to leave her husband and daughter. Despite her anguish, she made a new life and mission for herself in England helping victims of sexual exploitation.
Now, over two decades later, her estranged husband has returned to reclaim her. Their love is more powerful and passionate than ever before. And John Sinclair is determined nothing will come between them, no matter how difficult their past and present roads may be.
Angeline and John share a love that is rare and precious. Will they confront the ghosts of their past to build a better future? Or will a murderous madman destroy any hope they may have?
