The Illustrated Man by Ray Bradbury || This book took me a rather long time to get through. Mostly because it just didn't grab me, so I almost didn't finish it. I really love Ray Bradbury but I have a hard time with short story literature. Which is unfortunate since that is what the majority of his work is, short stories. The Illustrated Man is constructed of 18 short stories as well as a prologue and epilogue that kind of tie it all together. With every narrative, I either loved it or couldn't wait to finish it. I have no in between when it comes to short stories. A few of the ones I really loved were The Veldt, The Man, The Fox and The Forest, and Marionettes, Inc. You can look up and find just those stories if you are not interested in reading the whole book.
If I were going to recommend a Bradbury book it would be Dandelion Wine. It is also a book of short stories but they are all connected and weave in and out of one another. It's one of the most colorful, inspiring books I've ever read. So if you're looking for a Ray book, check out Dandelion Wine.
