Want an author visit but can't afford it for your school? Check out DonorsChoose.org. It's a fund-raising site especially for schools and teachers. And you can apply for all sorts of things, not just author visits. Although that would be a good one.
Want to know about my school visits? Go to VISITS (and email me for pricing at elizabeth at dulemba dot com). Thanks to my agent for turning me on to this one!
