Save me the Waltz was the book. I had heard of it, but never read it. In Tender is the Night, there was a characternamed Driver that I think was based on Zelda.

I believe she and F. Scott had children too, and he died young, early 40s I think.

A co-worker also told me that the computer/video game Legend of Zelda was named for her. I've heard of the game, but don't know anything about it.
