I’ve just finished reading this, it has taken a LONG time because its a very very LONG book. I was expecting 100% science fiction, because that’s what I had read of Bradbury in the past, but this lot is quite different. Most of the stories were written in the mid 20th century, and yes, there are some science fiction shorts amongst them (Bradbury was quite fixated on Mars). This volume is a mix of scifi, horror, mystery, madness and general fiction.
Volume 1 of the short stories holds ones interest from start to finish. Read it!
