I found that one a bit more difficult than the Silmarillion.
But if you liked Silmarillion (which I did), there is some enjoyment in Unfinished Tales too, imho.
Worlds in Collision. I found my old copy from thirty odd years ago and thought I'd give it another try. I didn't finish it the first time, and I doubt I'll finish it this time.

The Diamond Age - Neal Stephenson
I finished and enjoyed Snow Crash a few weeks ago.
I'm currently reading The Pluto Files by Dr. Neil Degrasse Tyson and re-reading The Last Continent by Terry Pratchett.
I've also got the new book, Nation, which I'll be starting next week.
The Far Side of the World, by Patrick O'Brian. Annoyingly, I've lent the next few books in the series to a friend who lives out of town, so I'll have to stop after this.
Oh no! Maybe you could go back and start at the beginning again till the friend returns them. Most people (me) think the second, third or fourth voyage is even better.
