With just five dollars and a knapsack to her name, fifteen-year-old Harleen Quinzel is sent to live in Gotham City. She's not worried, though--she's battled a lot of hard situations as a kid, and knows her determination and outspokenness will carry her through life in the most dangerous city in the world. And when Gotham's finest drag queen, Mama, takes her in, it seems like Harley has finally found a place to grow into her most "true true" with new best friend Ivy at Gotham High. But when Mama's drag cabaret becomes the next victim in the wave of gentrification that's taking over the neighborhood, Harley's fortune takes another turn. Now Harleen is mad. In turning her anger into action, she is faced with two choices: Join activist Ivy, who's campaigning to make the neighborhood a better place to live, or team up with her anarchist friend Jack, who plans to take down Gotham one corporation at a time.
