On Greens website under questions about Will Grayson, you can find a questions about his experience about collaborating. You can also find a questions about his experience of working with Maureen Johnson and Lauren Myracle on Let it Snow.
Q. What was the experience of collaborating like?
A. It was great. One of the things I find difficult about writing is that it can be extremely isolating: Ultimately, it’s just you in your head trying to make a story for people who will not see that story (even in the best case scenario) for years, and who may very well never see the story. Collaboration in writing is fun for me because I know that someone will see what I’m working on with each chapter that I finish, and there’s also something very invigorating about working with a writer you admire, and I admire David very much.
Q. What was it like writing Let It Snow with Maureen Johnson and Lauren Myracle?
A. It was so, so, so, so, so, so fun. I absolutely adore Maureen and Lauren, and we had a great time coming up with all the little threads that would weave through the story (like tin foil man). Writing “A Cheertastic Christmas Miracle” might have been the most fun I’ve ever had writing a story; I was inspired by Maureen to try to make it as zany as possible and inspired by Lauren to try to give it real heart.
