Stephen King and John Grisham are among the authors giving readers a chance to have a character in their forthcoming books named after them.
King's novel will be published in 2006 or 2007
Horror novelist King is selling off a name in novel Cell - which must be female if it is to be killed off.
Lemony Snicket is offering an utterance by infant character Sunny Baudelaire for the September auction.
Money raised by the Ebay sale will be donated to freedom of expression group the First Amendment Project.
Other authors set to take part in the literary auction include Amy Tan, writer of The Joy Luck Club, and romantic novelist Nora Roberts.
"Pronunciation or spelling may be slightly mutilated," said the Lemony Snicket posting on the auction site, referring to the "bushcheney" utterance in The Grim Grotto.
Courtroom drama writer John Grisham said the lucky bidder would have their name attached to a character portrayed "in a good light".
