I write. For entirely more info than you'll probably need on this topic, you might want to take a look at the Wikipedia entry (http://en.wikipedia.org/wiki/Diane_Duane), search at Amazon.com, or check my bibliography/filmography.
Otherwise, I just plain spend much too much time online. :) Go on, friend me. I don't bite. Please note, though: I have a lot to do around here, and can be very delayed about getting back to you on comments.
For those who may be interested, there's now an e-bookshop online at DianeDuane.com at which we're gradually rolling out all the books in my backlist to which I own the rights, in the major ebook formats. Additionally, we've begun bringing out international editions of the Young Wizards novels for those readers not based in North America who've wanted the ebook versions from Amazon or B&N.com, but haven't been able to purchase them because of territory restrictions.Also available at the shop are various short works and compilations. Newest at the shop: the revised and updated "Author's Cut" edition of <Stealing the Elf-King's Roses and the short-fiction anthology Uptown Local and Other Interventions, featuring (among much else) the only two Young Wizards short stories, "Uptown Local" and the new "Theobroma".
