The Trans-Atlantic Fan Fund is a venerable institution that sends sf fans from North America to Europe and vice-versa, to bridge the world's fandoms (there are other funds that bring together fans from other parts of the world). Frank Wu, Anne KG Murphy and Brian Gray are fundraising for this year's fund, and they've solicited many writers — Charlie Stross, Nalo Hopkinson, David Brin, Elizabeth Bear, Julie Czerneda and Mary Robinette Kowal and me! — to donate "tuckerizations" in forthcoming works for a charity auction. Tuckerizing is the inclusion of a real person's name in a fictional piece (previous tuckerizations from charity auctions in my novels include General Graeme Sutherland in Little Brother, Suzanne Church in Makers, and Connor Prikkel in the forthcoming For the Win; my god-daughter Ada has also been tuckerized in my story "I, Robot" and in Makers).
TAFF is also auctioning off a first edition of "Nineteen Eighty-Four" (!), and John Hersey's "Hiroshima."
It's a great cause, and great prizes that make killer gifts (how cool would it be for a kid to grow up with her name on a character in a wonderful novel?)
