What is Fight Club? Can't say because the number one rule is not to talk about fight club. Zayn is involved in this club, as well as manages it, for the person who started the whole thing. He is known as one of the best fighters around town. Harry is eighteen years old and new to the neighborhood. He's also very curious and comes across this fight club and Zayn. He joins to get to know Zayn and once he does the other fighters start to use Harry as Zayn's weakness.
