If you have any suggestions for further SF reading I'd be very grateful!
Bearing in mind that what one person likes may not suit another and that I have a liking for action, I'll just list some here, in no particular order and without trying to influence you to any great degree.
I'm now reread Ian Banks "Consider Phlebus" and really into it!
Isaac Asimov's (genuflect in the presence of greatness!) original 3 books in the "Foundation" series.
Robert Heinlein's "Starship Troopers" which was made into a rather mediocre film. He's also written a lot of other fine stuff.
Jack Campbell's "Lost Fleet" series. great reading although it does repeat action plots a little?
Larry Niven "Ringworld" series. and other stuff
Jerry pournelle "The Mote in God's Eye". and other stuff.
Scott Westerfeld "The Killing of Worlds" and "The Risen Empire"
Frank Herbert's first "Dune" You have to read it to understand!
David Drake's "Hammer's Slammers".
Gordon Dickson's "Dorsai" series.
Anne Leckie "Ancillary" series.
Arthur C Clarke (bow down low again) "Rama" series
William C Dietz "Legion of the damned" series
John Scalzi "Old Man's War" and linked books.
Jeff Vandermeer "Annihilation" series - a very different, slightly spooky, read.
Eyal Kless "The Lost Puzzler" and follow ons.
"Halo" novels by various authors.
J G Ballard "The Drowned World".
Peter F Hamilton "Salvation" series.
Dave Barra "Lightship" series.
Hope that'll do you for a start? Actually I'm finding it difficult to stop as more great reads keep coming to mind!
If you read any of them do let me know what you think?
regards
Jock
