Can’t find something to dislike about this book.
It seems to me written in the sincerest interest of exploring the life of Kurt Vonnegut by a dear friend. The book, written in second person, is a journey through the writer’s life. I imagined myself as Kurt, in old age or perhaps in some purgatorial state, hearing my life described back to me in the most tender and considerate way, through both the epistemological and plain chronicling. 
I encourage anyone with an interest in the life of the quintessential American writer to read this, if not to understand his life, to imagine what it may be like to be a writer through someone who has first hand experienced of the most destructive times in history. Especially insightful given the state of the world today.
