The Skies of Pern (Dragonriders of Pern Series)

Anne McCaffrey's Pern series has been running successfully for so long that most of the Dragonriders' original problems have been solved. In The Skies of Pern, she confronts her standard cast of characters with the consequences of those solutions, consequences that are a whole new set of problems. Now that the Red Star has been pushed to another orbit, there will only be a few more ravenous Threads descending from it for them and their dragons to fight--and what role will that leave for them? They have successfully reclaimed Earth's lost technology--and suddenly everyone with a craft that might be outmoded, or who is phobic about surgery, is on the rampage, sabotaging and smashing and making up rumors. These fundamentalist Abominators are sure that something terrible will happen if the old ways are not gone back to--and sure enough, fire descends, on cue, from the skies.

Anne McCaffrey's tales of genetically engineered dragons and a lost colony that has declined into feudalism are ultimately SF rather than fantasy because they are about finding solutions to problems, solutions that involve working with what you are given to start off with; The Skies of Pern is all about elegant solutions to credible problems. --Amazon.co.uk
