I am kind of a fantasy and sci-fi fan. Neil Gaiman is my favorite current author. I also like Stephen King's son, Joe Hill (even better than his dad). I'm about to get his short story collection, 20th Century Ghosts for .99 from Borders in ePub.
You might enjoy picking up some Jules Verne and Lafcadio Hearn for free. Hearn's Japanese wife wrote an autobiography, I think, but I couldn't find it on Gutenberg. Gutenberg has a notice they may be moving their servers today so, if anything doesn't work, try back.

Or try to get your Verne and Hearn on feedbooks. They have much less Hearn there, though.
