To Heist and to Hold — Christina Britton

A vigilante widow and a casino owner are both trying to bluff their way to a winning hand.

Heloise Marlowe has always forged her own path. As a former blacksmith and fencing instructor, she wasn't just going to sit around knitting after her husband died. The Wimpole Street Widows Society, a secret group dedicated to balancing the scales of justice, was a much better fit for her skills. Her newest mission: seduce the owner of the club Dionysus and gain access to the den's inner workings. She didn't mind putting her body on the line, but she wasn't prepared to gamble her heart.

Ethan Sinclaire has worked hard to clean up his club after the betrayal of his brother. But now, rumors are swirling that his club is just as crooked as before. He won't let anyone destroy what he's built, so when Heloise starts poking around, he decides to go all in, in hopes that she'll show her hand. Enjoying her company is the easy part. Keeping himself from falling -- that's a whole different card game.
