One of the main themes is friendship. Chloe and Rachel's relationship is central, showing the deep bond and the ups and downs in their friendship. Another theme is self - discovery. Chloe is on a journey to figure out who she is, especially in the context of her difficult family situation and her place in the world. Also, there's a theme of rebellion as Chloe often goes against the norms and rules in her town.
The main themes include identity. Chloe is constantly trying to define herself, separate from her past and the expectations others have of her. Love is also a theme, not just in a romantic sense between Chloe and Rachel, but also the love within families, like Chloe's complex feelings towards her mother. And there's the theme of growing up, dealing with the challenges and changes that come with adolescence in a small town.
