Author vs. illustrator

At the far reaches of Earth, high upon a mountaintop, a bustling city is under attack by a... cute little furball? Wait--what?! That's not right. The author wrote this book about a "ferocious beast," not a cuddly critter. Turns out, the book's illustrator has other plans. Can the author make a successful book with no pictures? Can the illustrator tell a tale without words? Or will this dueling duo get on the same page at last to create the ultimate happy ending? In graphic novel format.
