Infinite present. True story about love, happiness and disease Alzheimer

Sarah ninety years old, she has two sons and wonderful grandchildren, she lived an interesting life in which there were difficult times and happy days. But now Sarah hardly recalls moments from this life, often does not recognize loved ones, and in his own house he feels like a guest. It seems to her that she was left alone with something very terrible, that she wanders in the darkness, impenetrable and hostile, and around-strangers and danger. But for a moment this dusk is dispelled, and then Sarah recognizes in the man sitting opposite the man of her son. This book is full of tenderness, gratitude, unexpected humor and, of course, real happiness, which does not know oblivion.
