Writer's Block

Ralph Jeremiah Johnson Token stared at an almost blank sheet of paper. Two lonely words were written at the top: Book Description.
He scratched his head, looked out the window for a while, and then went for a walk. When he got back, the page was still blank.
“I don’t know how to describe this book!” he said to the heavens, as if the appeal would somehow summon divine intervention.
“Confound it!” He stared at the page, willing the words to appear.
It remained blank.
“It’s about me, and Mr Tolkien, and time travel…” He sighed. “I guess people will just have to read it if they want to know the plot.”
