Tracy is a 13-year-old girl whose personality shifts dramatically from a sweet, intelligent honor student to a reckless, rebellious teenager. Driven by a desire for popularity and craving acceptance, she is easily manipulated by her friend Evie into abusing drugs and alcohol. Her brother is Mason Freeland.

Evie is a manipulative, charismatic, and rebellious seventh-grader who acts as a "queen bee" figure, acting as the primary agent of corruption in Tracy Freeland's life. Known for her vanity and disregard for authority, she introduces Tracy to drugs, theft, and dangerous behaviors while acting as a "broken child" dealing with her own past.

Astrid is a manipulative, aggressive, and troubled teenager who serves as the antagonist responsible for leading Tracy, down a destructive path. She is characterized by her volatile, "mean girl" demeanor, rebellious behavior, and deep-seated insecurities that she hides behind a facade of defiance. Also a friend of Evie’s.

Noel is a supporting character representing Tracy’s life before her downward spiral. She is portrayed as a kind, loyal, and sweet friend who becomes sidelined and saddened when Tracy abandons her for a more reckless crowd.

Mason is the older brother of Tracy Freeland, acting as a cynical, witty, and somewhat protective figure amidst his family's chaotic life. While a rebellious, skateboarding, pot-smoking teenager himself, he is often seen as the "only sane man" compared to his mother's dysfunction and sister's rapid downward spiral.

Melanie is a complex, flawed character, depicted as a loving yet overwhelmed single mother and recovering alcoholic. She tries to connect with her daughter, Tracy, but struggles with setting boundaries, often allowing her own financial, emotional, and recovery struggles—along with her troubled boyfriend - Brady, to overshadow her daughter's neglect.

Javi is a popular, slightly older boy at school who becomes a target of affection for the main characters, Tracy and Evie. Is also one of Mason’s friends.
