I have a book called The Outlandish Companion that she and her editor wrote. It contains a glossery of all her characters and Celtic words, etc . . . I really hope JKR will come out with something similar when the HP books are over - althought the Lexicon is great.

Anyway, there are several chapters where she talks about writing and how she got into it and she gives tips on how to research (she had never been to Scotland until after this first book was published!) She has three kids and a husband with a good sense of humor and she's very Catholic and she loves to cook. I think you two would get along. :)
