I'm currently reading What Dreams May Come by Richard Matheson... i swear, this author is absolutely amazing. You can tell that this book has influenced other stories/movies (like Ghost... and of course the movie What Dreams May Come). Other book i read by him was I Am Legend, which obviously influenced movies such as Dawn of the Dead and 28 Days Later... and other undead/end of the world books/movies.
Previously to this i read Fevre Dream by GRR Martin... yes, the same author as Song of Ice and Fire, and although a completely different book, it's ABSOLUTELY AMAZING. I swear, you would think he actually lived the time and was simply recounting it... or at the very least was an expert on river steamboats and the culture. *boggles* my mind how descriptive and engaging the book was. It's not your typical vampire story, but that's why i like it (i hate all the erotic vampire stories that seems to be so common these days).
