Not quite a wife
(Book)

James, Lord Kirkland, owns a shipping fleet, half a London gaming house, and is a ruthlessly effective spymaster. Laurel Herbert gave James her heart as an innocent young girl, until she saw him perform an act of shocking violence. That night she left the husband who is far more than the fashionable lord he seems, and he let her go without a word of protest. Now, ten years later, a chance encounter turns passionate, with consequences that cannot be ignored. But as they try to rebuild what was broken, they must face common enemies and a very uncommon love.
