Heartbreaker's Bet. Better Than Baseball, #2

I need someone to help me become a heartbreaker. And I've picked you. Bettina Knox's dating life was a disaster. What she needed was some expert instruction on becoming the love-'em-and-leave-'em type. Luckily she found the perfect man for the job-a professional-grade flirter, adored by every woman he encountered. It was all fun and games until she started falling for her way-too-sexy teacher. So you want me to give you all my secrets for breaking hearts.
Even though I'm not convinced I've ever broken any. Troy Callahan thought he'd heard it all in his years of owning a popular sports pub. Then this sweet, sassy woman waltzed up insisting he was going to teach her how to break hearts. He'd been a wingman forever, so why not help her unleash her inner bad girl? There was just one problem: turning Bet into a heartbreaking assassin had somehow put his own heart at risk.
