Twentysomething master barista and owner of Portland, Oregon’s popular Ground Rules coffee cart, Sage Caplin is ready to celebrate her growing business at a weekend long maker’s festival, complete with live music, a cornhole tournament, 4th of July fireworks—and murder . . .
In addition to her beloved coffees, Sage is thrilled to be expanding her offerings in collaboration with the local whiskey company that is throwing the festival. And how better to launch their new product than with fellow entrepreneurs. But among the crowd of artists and creators, Sage is surprised to spot Left Coast Grinds owner Mark Jeffries, who has it out for Ground Rules. The distillery didn’t invite Mark and they apologize. But nothing can make up for the glare Mark aims at Sage and her co-owner, Harley. And that’s just a taste of what’s to come . . .
Soon Mark incites a loud argument with Harley and is ousted from the property. But later that night, Sage finds Mark's body by the Ground Rules Subaru. She knows that when investigators learn that Harley and Mark had a history of butting heads, Harley will be a prime suspect—and she’s right. But Mark rubbed many people the wrong way, and several are at the festival. Now Sage will have to filter through secrets, grudges, and blackmail to get to the bitter truth—and as her sleuthing heats up, the closing fireworks won’t just be the ones in the sky . . .
