I just came up with an idea I like so much that I feel a visceral need to share it with Nerdfighteria.
All of John's books take place in the same basic setting; suburban America. Because the characters are so alive and well developed, I've always wondered what would happen if they all met up. How would Hassan and the Colonel act around each other? What about Hazel and Margo? Miles and (John's) Will Grayson?, etc.
After wishing to read this story forever, I've decided just to write it, so I will. I'll probably post it on my little-used fanfiction.net page, http://www.fanfiction.net/~thebookemist
So, I'd like Nerdfighteria's feedback? Like the idea? Hate it? Do you have any specific characters you would like to see interact?
Also, if anyone has read a fanfiction like this before, I'd appreciate a link.
