Science Fiction

Ben Bova's Grand Tour series (around 20 loosely connected books taking place 50 to 100 years in the future) is a great read. My favorites in the series are Moon War (about a colony of people on the moon having to fight for independence from what's basically a UN with muscle to enforce international law) & The Return (the finale to the grand tour series).

Scott Westerfeld writes some interesting books to. If you want to read a really good novel read his Succession series. It's two books, 'The Risen Empire' and 'The Killing of Worlds' set 5000 years in the future. It's a bit hard to get into at first, from all the advanced technology that makes it a bit confusing at first (such as mini planes the size of a fly the pilots fly remotely). The two books were supposed to be published as one originally, but the publisher wouldn't publish it unless he split it into 2 because it was too long (it's over 800 pages total).
