Deep in the heart of touristy small-town Spirit Canyon, South Dakota, former journalist Zo Jones runs the Happy Camper gift shop, where she sells everything from locally made souvenirs to memorabilia. She even rents out mountain bikes and dabbles in the adventure industry-and sleuthing.

It's Memorial Day weekend in Spirit Canyon, and for Zo, that means the return of summer shoppers. It also means the return of her good friend Beth, who's moved back to the area to reopen her family's hotel, Spirit Canyon Lodge. Beth and Zo spent many childhood summers there, and Zo can't wait to reconnect and celebrate the Grand Opening. But the festivities go from bad to worse when a power outage knocks out the lights-and morning reveals a competitor's dead body found on the premises.

Soon enough, Beth is the prime suspect in the suspicious death. Fortunately, Zo isn't afraid to put her investigative skills to work and prove her friend's innocence. To start digging for information, she appeals to Max Harrington, a local Forest Ranger and unlikely ally. Though they've argued about Happy Camper's tours, they agree on one thing: Beth isn't a murderer. Stranger things have happened than their collaboration. But as the list of suspects grows, Zo will have to keep her guard up if she doesn't want to be the next lodge guest to check out . . .
