Kurt Vonnegut could touch extremely difficult topics such as a son becoming schizophrenic and going totally crazy at the age of 23, with humor and a delicacy and a never obvious attitude, that I've never seen in anyone.
When Mark, son, wrote a book about his recovery from the illness, Kurt sent him a foreword.
I remember reading this in 2010 in a local bookshop in Cannes, France.
It was one of the best things I ever read.
I eventually read the book. It was okay.
