His Wicked Secret (League of Rogues‪)‬

Audrey Sheridan is London's sweetheart, a position that allows her access to the ton and all its secrets. As the enigmatic writer, Lady Society, she is wild, reckless, and speaks her mind. She matchmakes wicked rogues with their perfect wives. But there's one thing she's failed to find since her debut. A husband for herself. And there's only one man she's ever wanted. There's just one problem: he doesn't want her. What's a lady to do to mend her broken heart? Run off to become a spy . . .

Jonathan St. Laurent is anything but a saint and certainly not husband material. He spent nearly his entire life as a servant to his half-brother, the Duke of Essex. He's trying to play the gentleman now, but it's damned hard when he's tempted by the ton's darling spitfire Audrey. There's something about her that makes him want to abandon the rules of polite society and show her just how wicked he can be . . . which is why it's better to avoid the minx altogether. When Audrey's plan to be a spy is discovered, Jonathan knows he must move heaven and earth to protect her while guarding his own secret . . .
