Well, I can tell you a little about some of them~
House Of Leaves: This is a meta-fiction book, meaning that it is a book within a book. The main storyline is a little hard to describe, but suffice to say that it is about a haunted house. The thing that separates this book from other haunted house stories is that neither of the two main characters ever set foot inside the house. The book starts with a short video called "The 5 and 1/2 minute hallway" which is about the owners of said house realizing that things aren't quite what they seem. The house is larger on the inside than it is on the outside, and there are rooms which seem to appear and disappear for no reason at all. This, and other data about the house on Ash Tree Lane has been compiled by an old man named Zampano. Upon Zampano's dying, all of his records are discovered by a tattoo artist named Jonny Truant, and it is along with him that you will dive into these old records. Are you confused yet? Like I said, it's a lot harder to explain than to just read it. Also, the book uses awesome techniques to make the reader feel like they're actually a part of the story. Pages where a character is running through narrow hallways have only a few words on them, to give the sense of frantically moving. The house's structure defies logic, so there are pages with text in small boxes, text written backwards, and all sorts of other interesting methods. Oh, and there are countless secrets hidden in the book, such as taking the first letter from each word in a certain passage to find an encoded message. These things aren't always obvious, and there are actually several "walkthroughs" of the book on the internet. Yeah. It's that awesome.
Invisible Monsters: This book is, like all of Palahniuk's books, the tale of a loner. Shannon is a former fashion model, who lost the lower half of her face to a gunshot. She travels along with a bunch of fucked-up people who do equally fucked-up things, such as stealing drugs from the open-house tours of rich people. I can't really say anything about this book plot-wise, because there are so many twists that by the end you can't believe who these characters end up being. I will say that it is my favorite book by my favorite author, and hope that this statement alone will help you decide to read it or not.
Cat's Cradle: Kurt Vonnegut books give me a unique feeling when I read them. It's a mix of hopelessness and hilarity. It's a feeling that no other author gives me, and I can read any of his books with confidence that I will be pleased. Cat's Cradle is mostly a story about Bokononism, which is a fictional anti-religion started by a man in the Caribbean. The rest of the story is about Ice-Nine, a fictional chemical compound that will instantly turn any liquid it comes in contact with into more Ice-Nine. I'm starting to realize that either I'm no good at explaining books that I like, or the books that I like are hard to explain.
Fingerprints Of The Gods: This is a non-fiction book about Graham Hancock taking a journey to ancient monoliths around the world, and trying to come up with a meaning and connection between them. A lot of the science in the book is bogus, and should be taken with a grain of salt, but the coincidences and unexplained mysteries that he goes into are incredible. The book deals a lot with precursor civilizations, such as the Maya and the Olmec, and talks in part about the 2012 apocalypse. In short, Hancock takes myths, artifacts, monoliths, and local tales and spins them all together into one cohesive story of a former civilization. There are parts of his theories that I believe in, and others that are pretty out there. It's a great read though.
