It's time. Mary, an ex cop, and her husband Pete, a former librarian, have decided to move into a retirement village. Selling their beloved house should be a clean break, but the past, it seems, has other ideas. A detective calls with new information about the case of their son, Will, who died in an accident forty years earlier. Mary finds herself returning to the last months of her sister's shortened life. And Pete is haunted by memories of his late mother, who developed delirium and never recovered.

An unforgettable novel of rare power and grace, Delirious poses the questions we all eventually face, if we're lucky - or unlucky - enough. How do we care for others? How do we face each new phase of life? And how do we ever cope?
