When Ali gets the worst news in the world, she knows the one person she can count on. He's encouraged her to be brave when she wasn't. Made her believe in herself when she couldn't. Now, she needs him to help her navigate the darkest days of her life. So she writes to him one first - and last - time. When Tom receives a fan letter, it's like nothing he's ever had before. It sets off a chain of letters - and events - that neither he nor Ali could ever have predicted. A dream is a wish your heart makes, and sometimes wishes - and dreams - come true.... don't they?
