A good deal
I recently read three novels by A. E. van Vogt, one of the early masters of pulp science fiction. I picked up this three book set at Book Smart on a whim, and it turned out to be a good deal. For four bucks, I got The World of Null-A, The Voyage of the Space Beagle, and Slan. I was mostly curious about The World of Null-A, and I'd never even heard of Voyage of the Space Beagle, but all three books ended up being enjoyable reading. This is old skool sci-fi, where the heros are men, the science isn't, and the pages turn quickly and the writing best not dwelled on. But very entertaining.
