HOLD ME CLOSER: The Tiny Cooper Story by David Levithan
Here's the description from David's Goodreads interview for the book:
When YA favorites David Levithan and John Green decided to collaborate on Will Grayson, Will Grayson, their hit 2010 novel of two very different high schoolers with the same name, they had no idea that another character—the irrepressible Tiny Cooper—would end up stealing every scene. Now David has given Tiny the attention he deserves in a new solo novel-as-musical, Hold Me Closer, the Tiny Cooper Story. Yes, both Will Graysons will make an appearance (though for privacy's sake, Tiny has given one of them a pseudonym: Phil Wrayson) and, according to David, we'll get to see a side of Tiny that has not yet been revealed. "Absolutely," he says. "For example, in Will Grayson, Will Grayson, we didn't see the moment Tiny was born. But we do in Hold Me Closer."
