Congratulations, Cory! And congratulations to his editor, Patrick Nielsen Hayden.
I am especially pleased at the book's success because not only is it a terrific book that I read from cover to cover in essentially one sitting, but it is a book that the world really needs.
Cory has set up a system whereby people can donate copies to teachers and librarians who request them. After you've bought a copy for yourself, why not buy one for a teacher or librarian who needs one?
