The Wilderness, By Samantha Harvey

Many novels have documented the trials of living with dementia, but this mind-bending debut throws us straight into the skewed recesses of a suffer's brain. The 60-year-old Jake has always had an uneasy relationship with his past, even before the onset of Alzheimer's.

He has been a husband, father, son and lover, but is haunted by regret. Looping together memories of conversations, long-ago vistas and sacred objects, Jake spins himself a hyper-real narrative which may, or may not, have anything to do with his past. An exhilarating trip, but for the thought this is a place some of us might visit one day.
