The Red-Hot Stakes by Maren Jenner

Book three in the Sweet Nothings series
Gina Rossi is always up for a good bet, until she is gambling with her heart.

Gina’ s one dream is to buy her own bar and run it the way she wants. But until she finishes her business degree, she is stuck working at The High Five, listening to bad karaoke and serving bland chili.
When the annoyingly handsome Liam Davenport decides to become a regular patron, Gina couldn’ t be more frustrated. Sure he tips well, but he pushes all her buttons. The only time she can stand him is when he sings karaoke, and she loses herself in his velvet voice.
The last thing Gina expects is to fall for the brash, arrogant man, but he slowly wins her over. Soon she can’ t imagine being with anyone else. When a mysterious blackmailer threatens to tear apart their new life together, she has to gamble with the highest stakes of her life. Her heart.
