Teaching a new player, male or female, is dependent on the individual, and how they learn best. Some will learn best with a manual, others if they have a guide.
Certainly, showing her the manual won't burn out her eyes.

Lend her the book, stress that she doesn't have to read anything if she doesn't want to - just a get a feel for a few things, read what sounds interesting, perhaps the races & classes. Tell her she's not expected to know it all and that at the table, they will help her through.
Draw parallels to works she already knows - stress fantasy movies or books so she can get a better idea of what this will be like. And on game night, if you can't be her guide, find one of the players who will take this seriously, won't be too pushy or domineering, to help her through the process.
I was a learn from the book type, too, when I started. If she's intellectual, she's probably very used to that format. Just don't require it. I would imagine, though, that if she gets fired up when she flips through the book, she may read it anyways, leaving you less work to do. Then it will be a matter of acquainting her with how your group works, and what it's really like to play the game, not just understand the rules.
