Authors have a lot of fantasy scenarios, some of which are even printable. (Insert 50 Shades of Grey joke here.)
A definite fantasy scenario is having one of your favorite authors read your manuscript and like it enough to blurb it. The chances against such a thing happening are pretty huge for many reasons, not the least of which is that authors are busy with work of their own.
But my editor, Arthur A. Levine at Scholastic, has taken special care with The Game of Love and Death. The result is something I wouldn't have dared dream of. A long list of some of my very favorite authors not only took the time to read my book, they liked it. I've been having a Sally Field of a time processing it.
I've linked to each of these authors' sites, so do check them out if you haven't read their work. It's an incredible slate of writers—so great I've been almost too embarrassed to say anything.
