Well, maybe because it's not a nonfiction book. [She laughs a little and scoots over closer to the giant owl--almost like she's completely comfortable being around large birds--and starts flipping pages. Finally she gets to an engraving printed in the book and she shows it to him.]

It's a story about explorers journeying to-- well, the center of the Earth. Obviously. Nobody can travel to the center of the Earth of course, but it's always been one of my favorites even if it's not actually possible.
