So, I don't really like realistic books

I started reading Cast of Shadows by Kevin Guilfoile. It's very well written (and set in Chicago!) and I want to like it, but it's just too realistic. It was creeping me out. Well, not really creeping me out, I guess, but just making me uncomfortable. Which I'm sure it's supposed to do. But I had the same kind of experience with The Bone Collector (which is surely not even on the same level), and though I ended being okay with that book, I didn't get over the uncomfortable feeling of it being too realistic. I don't want to be worried every time I get in a cab that the cabbie is going to kidnap me. And, for now at least, I don't want to think about the horrible thought of cloning an unidentified killer, and letting him grow up in society, just to see what he looks like.

So, now I'm trying to decide between three "first of a series" books: Pawn of Prophecy, The Scions of Shannara, and A Game of Thrones. I'm leaning towards the first because I know that the series is only 5 somewhat shorter volumes, as opposed to the Heritage of Shannara, which is 4 slightly longer books (though the total probably isn't that much longer than the Belgariad), and The Fire and Ice series which starts with an 800+ page book, and has at least 4 books.
