Rose may be in her eighties and suffering from 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 assisted living facility, musing on the staff and residents, and enduring visits form her emotionally distant children and granddaughters. But when her friend is found dead after an apparent fall from a window, Rose embarks on an eccentric and determined investigation to discover the truth and uncover all manner of secrets...even some from her own past.
