Gambling with His Heart by E.E. Hamm

Love is supposed to be easy, unless you’re in love with a convicted felon.
Anna Larraby was a quiet woman with a quiet life. She wasn’t the wild and crazy sister, but the respectable and responsible one. Until her boss sends her to Vegas for the weekend.
What happens in Vegas should stay in Vegas. Especially when you fall into bed with a bad boy who knows how to keep a woman up all night. When she realizes too late that her one-night hottie spent the last seven years in prison, she hightails it back to New York.
Though she tries to forget his dimples and superman curl, fate has other plans. Ben shows up on her doorstep with a business proposition. The only problem is, all Anna wants to do is mix business with pleasure.
