Enter the world of the most notorious gambling den in London, where matches are made... unusually. Welcome to the world of THE LYON'S DEN: The Black Widow of Whitehall Connected World, where the underground of Regency London thrives... and loves.

Marrying his childhood friend wasn’t part of the mission.

Six years is a long time to wait for her past life, but Annabeth Greene isn’t waiting for the idiot Duke of Grandfellow or for Bow Street to discover what happened to her brother. Anna uses her new connections to learn where he was last seen, but not even her brother’s viscount title can save her when she’s caught breaking into the office of the Widow of Whitehall. The Lyon’s Den proprietress demands a cruel favor in exchange for Anna’s freedom. Which is no freedom at all.

Jackson Cole’s investigation into the Lyon’s Den and its involvement with a violent counterfeiting ring goes sideways when a suspicious turn of the cards lands him squarely in the Lyon’s clutches. Now, he must marry some woman of the widow proprietress’s choosing or risk blowing his cover. If only Miss Greene were just some woman. Six years is a long time to pine for the woman who broke his heart. Now, she is to be his bride. The problem is, the girl he knew as a boy has become a woman too clever—and insulting—to resist. If he is to hide his connection to the Home Office, he’ll need to keep his secrets locked up tight, no matter how dangerous she is with a lockpick.

A forced marriage. Two investigations. And a second chance at love. If only they can avoid the attempts on their lives long enough to stop fighting each other and learn to love again.
