Anyway, this is not just about how wonderful Dan is (which he is) but about School Visits. Now I did a little piece on school visits featuring Doomspell author Cliff McNish a while back - school visits are a big deal for children's authors because it's a cool way of getting in touch with one's readers etc etc. Of course, it doesn't hurt either that you could make a little bit of money to supplement your non JK Rowling advance.
So here's Dan's truly super cool video about a week long visit to a school for gifted children in Virginia. We can all learn a thing or two about marketing ourselves here.
