You know how it is: You read a certain book, you like it a lot, and you think, Maybe I should try to get in touch with the author. This being the 21st century, you hunt up the correct website, you send an email, you say, Hey, it would be cool if you could come and visit my school sometime.
The author reads your email, is impressed by your coolness and your enjoyment of her book, and writes back to say, Hey, I’d love to visit your school. And, because your school is also very cool, the motion is seconded, and carried, by the administration.
And the author makes plans to visit you in February, and looks forward to it a whole lot. The End.
The moral of our story? You never know where a book is going to take you.
