Isabella Tomlinson used to know her brother like the back of her hand. Key word "used". Now, he might as well be a complete stranger. She doesn't want anything to do with him; not after he left her for the fame and money 3 years ago. But when she's forced to live with Louis and his bandmates, can she and her brother finally patch things up? Will she be able to fight her feelings for a certain someone in the band?
