Ground Rules Mystery Series

Portland is famous for its rain, hipsters, craft beers...and coffee. Sage Caplin has high hopes for her coffee cart, Ground Rules, which she runs with her business partner, Harley - a genius at roasting beans and devising new blends. That's essential in a city where locals have intensely strong opinions about cappuccino versus macchiato - especially in the case of one of Sage's very first customers. Sage finds the man's body in front of her cart, a fatal slash across his neck.

At Campathon, an annual eco-friendly festival held on a farm outside of Portland, fans celebrate the Pacific Northwest's music scene in quintessential PDX style-with gourmet food carts, reusable utensils . . . and lots of coffee. How else to get through three days of nonstop entertainment? Sage has scored a coveted place for her Ground Rules coffee cart thanks to her new-ish boyfriend, Bax, who's friendly with Maya, one of the musicians performing.

To top off her coffee business, Sage is now helping out with her boyfriend Bax's gaming company. Conveniently for Sage, it's located next door to her Ground Rules Roastery. That makes it easy for her to pitch in with Bax's employee team-building event. The plan is to boost morale with a scavenger hunt. And it seems to be going well—until Robbie, a programmer known for being a prankster, turns up dead in Sage's roastery.

Ground Rules isn't the only newcomer set to open in Portland's grand new Button Building. Fortunately, most of the fellow micro-restaurant owners and patrons are great-with two exceptions. There's Rose, a true-crime podcaster and active TikToker who's pestering Sage for an interview about her estranged con-artist mother; and Bianca, the familiar and perpetually unpleasant owner of Breakfast Bandits. Bianca is abrasive to everyone, so Sage doesn't feel singled out . . . Until Bianca falls dead at the building's grand opening-a to-go cup of Ground Rules coffee in her hand.
