She holds the verse in the palm of her hand and tells a story she died in.

When Megan dies, she leaves a promise with her twin Emily: 'I'll weave a song for you...it may take a while, but I'll come back to you Em, somehow'. Her song threads a tapestry, spinning through a mosaic of memories and weaving into the present day, touching the lives of Alice and Jon.

The Cafe by the Oak is in the heart of Crayshead, a Cornish seaside town with a sleepy tortoise, a vocal parrot, and a dog named Wellington. Emily is charmed by Alice, an old lady with secrets hidden behind the walls of a convent. Jon's life lacks purpose. After taking up a new teaching post he feels settled enough to begin unravelling his past, but when he finds something he isn't looking for it causes him to question everything.

Emily seeks comfort in her art, reflecting on her childhood, and helping Jon pursue his past. And as Alice slowly reveals her secret, Emily breathes life into a painting on canvas... Can Megan weave a song without leaving them all with a sense of betrayal?
