The core of it is to tell a story
Not sure this is such a foregone conclusion among all gamers. Storytelling is really just one style.

Quite so. If the players already know how "role playing" works, the rules are just there to ensure everyone plays fair and what ruleset is used is immaterial.The rules are just for character generation and conflict resolution. Ultimately, only one person at the table needs to know those (it helps to have everyone else know them but it's not necessary). That person (not always the GM) can nurse everyone else through at the table.
There is no better introduction to "what RPG gaming is all about" (at least for fantasy adventure roleplaying games) than the Moldvay Basic D&D book (the red book with the Erol Otus cover art). It's 64 pages, has evocative descriptions, a simple, solid rules system and great examples of play. Better yet, if you don't own a copy, you should be able to score one for less than $10 on eBay, Amazon.com or NobleKnight.She wants something she can read and get an understanding of what RPG gaming is all about.
If she likes Dresden Files then it would be a good game for that. All you need is Yourr World, and lots of that she doesn't really need to read. The Buffy RPG also does a good job of introducing role playing to new people. Frankly, while I love D&D I never felt it did a good job of addressing new people in the core books.

Quite, and certainly not a universal style. It's certainly not my favorite nor the one I most indulge in. And it is definitely not "the superior style" (the correct and best style is always the one that the group has the most fun with).Storytelling is really just one style.
