A wickedly funny and genuinely moving novel about memory, language and love, perfect for fans of Richard Osman and The One-Hundred-Year-Old Man Who Jumped Out the Window.

In the beginning is the whatsitsname. The woman in the car park. She wears a nightgown and lies on her back, looking up at the sky. The nightgown is white and embroidered at the neck with blue . . . what do you call them? Forget-me-nots. A small crowd is gathered around her. All in their unicorns. Uniforms. All younger than the woman, much younger. They look at each other. They look up at the sky. They look down at the woman. They whisper.

Rose is in her eighties and has dementia, but she's not done with life just yet. Alternately sharp as a tack and spectacularly forgetful, she spends her days roaming the corridors of her aged-care facility, ruminating on the staff and residents and enduring visits from her emotionally distant children and grand-daughters. But when her friend is found dead after an apparent fall from a window, Rose embarks on an eccentric and deeply personal investigation to discover the truth and exposes all manner of secrets - even some from her own past.

All the Words We Know is a wickedly funny and genuinely moving story about loneliness, language and how we make sense of the world.
