Non-Fiction - The Making of the Atomic Bomb by Richard Rhodes. He won a Pulitzer for it, and it is incredible.
Science Fiction - Larry Niven and Jerry Pournelle wrote three books in the late 70's and early 80's that I consider to be great. The Mote in God's Eye, Lucifer's Hammer and Footfall
Recently I read 7 books by Ian Douglas, who appears to be a pseudonym for William H. Keith, Jr. It's actually three trilogies (only one book is out in the third), and greatly enjoyed them. They are called The Legacy Trilogy, The Heritage Trilogy, and the Inheritance Trilogy (only one book out). I'm looking forward to book 2 of the latest trilogy wheneven it comes out.
Freehold and The Weapon by Michael Z. Williamson paint an interesting picture of a UN dominated future where one colony refuses to knuckle under to the UN iron fist. Freehold can be downloaded free from the Baen Free Library. Lot's of good Bolo books by Keith Laumer and others who have picked up the franchise for a few stories or even a book.
As you can see I'm a bit heavy into Science Fiction. If you haven't explored that genre, you will find a lot of good stuff. Most of the movies are BS.
Thank you, I haven’t read much SF but would love to try that, they sound great and the Rhodes book does too. And thanks for the download info too !
I'll second that, and add the Ringworld and Rama series to the list.
You forgot Retief of the CDT, you scoundrel! :-)
Cheers!
