Readers met Mrs. Henderson in Spilled Coffee.

Her story comes forward in Spilled Coffee and the Amber Leaf.

As Parkinson’s disease dementia begins to loosen her grip on memory, time folds in on itself.

Sarah Henderson discovers that her garden holds a mystery, and the ordinary world becomes strange.

This is not the story of watching someone disappear—but of what it feels like, from the inside, as the self begins to slip and psychosis steps in.
