I Don't Want To Say Goodnight (All Time Low Fanfic)

Alex didn't realise that one letter from a fan could change his life, but it did. When he reads Mia's letter he would do anything to get to know her better. As their friendship and romance blossoms, he finds she's the one girl that he could happily spend the rest of his life with. But she's also the girl who's time is running out, and there's nothing he can do to stop it. Is there any point to a relationship when everyone already knows how it's going to end?
