Oh, what a terrible discussion topic. ( ;-) )

Reading through it I'm reaching for my Kobo (a 'Kindle' type device) thinking that I must re-read A,B,C & D, and probably also X,Y & Z.
This could prove expensive.

Of course, time is against me. (Anyone got a time machine?)
There are certainly books, novellas & short-stories that I need to read from the 'Hugos' short-list ready for this year's Worldcon in Dublin the first time Worldcon has made it to Ireland.

Over the years I've read a lot of great SF & fantasy. Some of the stuff I've read was 'not-so-good' but I don't begrudge the time spent. If you manage to avoid reading any of the 'not-so-good' stuff you miss the chance of a basis of comparison.

I won't add any names to the above until I've checked my current reading list, and had a chance to compare it to what's already listed.
