A Rogue of One's Own by Evie Dunmore

Lady Lucie and her band of suffragists finally have the funding to control one of London's major publishers, intent on using it against Parliament. Who could have predicted that the one person standing in her way is her old nemesis and London's undisputed lord of sin, Lord Ballentine? Or that he would be willing to hand over the reins for a night in her bed. Soon Lucie is trying to out-maneuver Tristan in the boardroom and the bedchamber.
