Currently reading Rise of Endymion by Dan Simmons, the fourth book in his Hyperion cantos/series. I've been really impressed with this series. For the first point, it has a really well thought-out mythology. But what I really appreciate is that though the story is gripping, there is still room enough for Simmons to discuss his philosophy and thoughts, making it thought-provoking at times. It looks as if there is an upcoming film adaption of the series, so we'll see how that goes!
Great SF series; Hyperion being better than the Endymion books, imo. Do really enjoy Simmons. Try reading The Terror in the middle of winter. I'm currently reading The Scar by Mieville. Is it good? Yes!
Also trying to make it through Our Mutual Friend, by Dickens. I've been chipping away at it for about a year, and I might just give up...
My hubski review of the series mk, I'm not sure why, but a hubski-search of "hyperion" didn't find this link for me. Surely it should have?
