John Roe's witty and lyrical memoir is an almost-perfect love story ... until the arrival of the demon. As a bright young student, future English teacher John found Ella, a woman who both matched his intellect and would help keep his feet on the ground. Together, they shared a wonderful marriage: they were lucky. But when Ella began to slip into dementia, their good fortune turned ferociously dark. John labels the dementia that stole his beloved wife as 'the demon': a malevolent force that destroys lives and extinguishes happiness. British neuroscientist Joseph Jebelli predicts that dementia will, unless we find a cure, affect one third of the world's population over the next seven decades. Until there is a way to cure or prevent it, the 'demon' of dementia has to be faced down. This passionate, immersive memoir takes the reader inside the emotional rollercoaster of losing a loved one to an outside force you can neither halt nor control.
