See the title; I'm just reading really damn good books lately. Not all of them are mindscrew, see that Birds of Prey underneath this on the posts, but most of the SF ones are. There's a reason that for the moment I've been reading nothing but dense and sometimes heavy books - they're just more satisfying.
Examples?
Hyperion and The Fall of Hyperion by Dan Simmons. They're actually one book in two. The first one is like a series of badass novellas, in which the scale of the story becomes greater and greater, but the second book makes that insane, to the level of a cosmic Dune story.
The difference between Hyperion and Dune? Hyperion isn't as suited for roleplaying in its setting, as there is no other way that setting could work. It also has the most terrifying mastermind idea I've seen in books in eons. It's just brr. Gets me on a primal level, it does.
Spin Control by Chris Moriarty. The millions-of-mind-in-one Cohen guy gets POVs, Li smokes like crazy in a crater, seventeen year old girls become cold soldiers like Rei Ayanami, online games, an entire homosexual culture that absolutely worked for me, and there's lots and lots of political spy intrigue.
Verra fun. The child soldiers boggled my mind. Moriarty has got to watch some anime to come up with that.
The Guns of August by Barbara Tuchman. I felt like I aged reading this book, and that is not an exaggeration. Because of this book, I now have a deeper interest in WWI... or, as I'm very careful to say now, the Great War. It isn't fun disturbing, but I think I needed to read it.
I had to pause between the diplomacy and the war parts of it. Sir Edward Grey's speech about England defending Belgium absolutely boggled my mind.
Last Call by Tim Powers. Strung out gamblers fighting gangsters. Sound like a contemporary crime story? This is Tim Powers. There's tarot cards, The Waste Land allusions, lots and lots of allusions, and surreal imagery I'm definitely going to be looting when I write my own bizarre western.
Strangely, it's also extremely like American Gods, another dense book. Ozzie, at the start of the book, seemed a lot like Mr. Wednesday. My theory, considering the dates of the two, is that Gaiman went "I can write a book like this!" and created an even more astonishing one.
Some of the minor characters were annoying, but I really liked the heroes. It was quite fun going on a road trip of words with them.
What am I reading now? The Rise and Fall of the Third Reich by William Shirer and Revelation Space by Alastair Reynolds. Both of them are amazing reads. Oh, yes, I am very into the density. And I don't think there's a coincidence that the majority of these have won various awards.
