In Love by Amy Bloom (Granta Books, $32.99)
Amy Bloom's husband Brian was diagnosed with Alzheimer's in his mid-60s. His cognitive decline was obvious (after putting it down to other causes) and rapid.
This is the story of their journey from suspicion, to diagnosis, all the way to getting on a plane and arriving at Dignitas in Zurich.
For those unfamiliar, Dignitas is a non-profit organisation offering accompanied suicide to those with terminal illnesses.
It's very, very difficult to get the 'green light', even a provisional one, and the couple, increasingly Amy alone, understandably have to jump through a multitude of administrative hoops.
