Another reviewer rated it as 'excruciatingly detailed'. That is an understatement. It was excruciating to read. I am rarely put to sleep by a book. I simply couldn't finish this one. In spite of my dedicated, numerous returned efforts, I just couldn't do it.
I believe only serious Ray Bradbury fans that want to know every single detail of his life, correspondence, could enjoy this book.
