My grandmother, Evie Collier, is waiting on the front stoop of my cottage in a cardboard box marked Priority Mail.

Ruby tucks the six Ziploc bags of cremains into her vintage bread bin, topping it with a cheery daisy bloom. Her spiky-haired grandmother, Evie, has rocked leopard-print leggings and sipped minty Grasshoppers for the last time. After eighty-six full-throttle years, Evie screeched into death, but not before creating a funerary adventure. A series of carefully crafted puzzles and Evie’s instructions arrive at Ruby’s cottage. Solve to determine where to spread my ashes, discover the secrets I couldn’t share, and claim your inheritance. If you still want to.

Chalking up the cryptic message to their grandmother’s penchant for drama, perpetually sunny Ruby and her freshly divorced, cynical twin brother, Roddy, dive into the challenge. Ruby enlists the help of Marty, her wannabe suitor and adorably nerdy journalist, Millicent, a cookie-wielding docent, and—despite Roddy’s warnings—a sketchy mystery man from Evie’s past.

The solutions lead throughout Lancaster County (from historic factories to Amish dry goods stores) and back in time to the era of rollicking speakeasies and bone-crushing unemployment. The twins glimpse a 1930s Evie—young, spunky, and definitely not the woman they thought they knew. Though the revelations become increasingly concerning, only when the whiff of murder swirls around her grandmother’s secrets does Ruby’s shiny worldview dim. The truth is a bombshell and Ruby’s life will never be the same.
