A Cup of Fate by Alexis Gorgun

Alexis Gorgun, the author of the ‘Cup of’ series, is back at it in this laugh-out-loud and steamy rom-com that throws Ruby, a sassy barista, into a cocktail competition where Theo, a suave bar owner, reluctantly becomes her mixology mentor.
When I hit rock bottom, my well-meaning sister signs me up for a cocktail competition. The cash prize is life-changing, and I’ll do anything for that money. There’s just one problem: my expertise in cocktails extends to sipping, not mixing. And when I turn to my bartender friends for help, they all refuse to train me.
In order to win, I have to turn to my old fling, Theo Watson. We ended on sour terms when he wanted something more than an occasional hookup. But his demand was downright impossible when I don’t believe in love or relationships. Now I must swallow my pride and ask him for the impossible—to train me for the competition.

What the hell has my sister gotten me into?
