Eight years ago, a nasty fall forced Mattie Samuelson to live in an assisted living facility called Silver Pines. She's always maintained that someone pushed her, though her daughter, Heather, chalks it up to a simple slip in the rain. One fateful day, Heather makes her mother promise to stay in the house and out of Oregon's miserable weather. When Mattie breaks her promise and turns up dead in a suspicious accident, Heather can't forget her mother's ominous belief that someone tried to kill her. Her grief nearly overwhelms her, but she can't let Mattie's death go unresolved. She plunges into her own investigation.

A missing fortune and a discarded teddy bear are somehow entwined in Mattie's murder, but how? Heather must figure it out and bring order to an assisted living center where assisted dying has become the norm ...
