Unforgettable: A Son, a Mother, and the Lessons of a Lifetime is the story of the author’s mother, told from the miserable ICU where she died, and punctuated by the tweets her son sent while sitting (and sleeping, badly) in her room. You will need to get by the occasional uncomfortably intimate details of her love life, but her spirit, determination, and astute upbringing of her son are wonderfully inspiring.
There is an interesting subplot of how terrible end-of-life care can be, even in a good hospital, and of how nurses and custodians seem to provide more comfort than the physicians who just do not want to talk about death. But the mother is the star!
