Some of the illustrations are fantastic, worth it just for those.
Otherwise this is a nice coffee-table book that summarises the life and works of Stephen King, and how one influences the other.
Like so many of his bios may of the newer works are overshadowed and barely given a paragraph (The Institute, and so many more) There’s no new information or revelations to be had here, but it’s a nice collection of plot summaries and a few anecdotes.
