So what's the story about?
The single word theme might be redemption.
Here's the longer version:
Nathan Stiles has a problem. OK, maybe he has more than one problem. Once America's most popular romance novelist, Nathan has not published in over five years. As the finish line looms for perhaps his last chance at publishing another book, Nathan finds himself in terrible shape, both mentally and physically. He also finds himself without a place to live when his wife tells him she wants a divorce. A visit to his old high school cross country coach may solve his homeless problem, but are Coach Willie's lessons enough for Nathan to figure out how to rewrite the ending to this story?
