Yeah, The Silmarillion is a good read if you're a Tolkien fan. Personally, I could never wrap my head around it because I found it too difficult to read. Anyways, here are some excusions by way of me:
Project ARMs: It's a great manga following the adventures of a young student with an near-robotic arm, who has various kinds of people chasing him down. I think it does really well in concentrating on character development, and the action is not too shabby at all. Best of all, the authors aren't afraid to go pass the cliché. It's my 2nd favorite manga following Death Note.
Battle Royale: If you liked the movie or book, manga's absolutely great. The art is attractive, and it's definitely a good read IMO. It's basically about an entire class that gets taken to an isolated island where they're forced to kill each other off until there's only one remaining.
Count Cain (or Godchild): I've honestly never read it, but my friend highly recommended it to me, and says it's her favorite manga. Wish I could say more <_<;.
Planetes: A very good science fiction read I think. I don't really like the art, but it explores some great themes and is highly accurate in terms of information/science. It's about a man's struggles with himself and his meager job of cleaning up space debris, and his desire to travel to beyond Earth with his own ship. It's only 4 volumes long, so it's pretty short. And it goes slow as well.
"A pistol is a tool to save people. It's not a weapon for murder.
" "Then save me by killing them!
" "That's kinda contradictory...
