Fantasy Books help needed!.

Not fantasy, but I'd recommend The Hitchhiker's Guide To The Galaxy. It's mainstream-ish. I mean, it's been around for a good while, but it's still a good read. Don't base it off of the movie that came out around ten years ago, that movie was crap in my opinion.

There is an online web series called WORM. My friend told me about it and it changed my life. It's essentially a superhero/supervillain story which makes you think a lot, and yes there is romance in the book. Granted, it is very very long.
