The best science fiction isn't necessarily about technology or space travel or aliens, but about ideas. Although these classic novels are some 40 years old, Alfred Bester's first two novels uphold this timeless principle and deliver a couple of great reads to boot. Now they've been reissued with new covers and introductions by Harry Harrison and Neil Gaiman. Bester won the very first Hugo award for The Demolished Man, a murder mystery set in a future society in which the institutional use of telepathy makes successful crime impossible. The Stars My Destination deals with hatred, revenge and the Great Man theory of history; it's considered one of the greatest science fiction novels ever written. Scientific fact and science-fiction fashion might have left these books behind, but few contemporary offerings in the genre are written with their thoughtfulness and craft.
