Shadow Show, the short story anthology in honour of Ray Bradbury is now out. I have a copy, but haven't had time to read it properly yet, just dip in here and there. Eventually I will get round to reviewing it. Meanwhile, there are other reviews out there to help you decide whether it is for you. This one from Ryan Britt at Tor.com gives a good overview from someone who has actually read it. The book was never intended to be a memorial to Bradbury, having been planned for months or years prior to Ray's recent death - but it looks as if it will serve as timely commemoration of the man and his writing. Those who don't know the history of the volume might be surprised to see that there is an introduction by Bradbury himself.
Paul Street has written a long article relating Bradbury's Fahrenheit 451 to our modern world. Much of what he writes is familiar: Bradbury's apparent prescience in his use of immersive TV systems, loss of literacy and increasing personal isolation through (for example) personal earphones. However, he makes a number of less familiar extrapolations, and manages to link in Facebook and other "evils" of the modern world. You may not agree with everything he writes, but it's a good piece. Read it here.
