Man with the Money [EPUB ebook] 

Notorious gambler Jack no longer gets a buzz from the risks, or the money, he takes at the card table. In fact, it bores him. Until one night he wins more than he ever bargained for.…His prize is the stunning Cara Taylor—she might be down on her luck but she certainly doesn't need rescuing by a maverick card-shark like Jack! Now she's stuck with him and she doesn't know whether to love him or loathe him. But, cut from the same pack, playing Jack at his own game is the most fun she's ever had!
