From bestselling author Cecelia Ahern comes Perfect , the thrilling sequel to her YA debut Flawed , about a girl who defies the strict rules of her society to do what is right. Celestine North lives in a society that demands perfection. After she was branded Flawed by a morality court, Celestine's life has completely fractured all her freedoms gone. Since Judge Crevan has declared her the number one threat to the public, she has been a ghost, on the run with Carrick—the only person she can trust. But Celestine has a secret—one that could bring the entire Flawed system crumbling to the ground. A secret that has already caused countless people to go missing. Judge Crevan is gaining the upper hand, and time is running out for Celestine. With tensions building, Celestine must make a choice: save just herself or to risk her life to save all Flawed people. And, most important of all, can she prove that to be human in itself is to be Flawed? "In a world without empathy and compassion, there’s nowhere to turn but to other Flawed people, a resistance of runners and revolutionaries, hoping to turn the tide of belief. Ahern’s previous adult books have all had a much lighter tone, so this series marks quite an interesting change of pace. Likely to bring up discussions of the current political climate and laws, this novel will definitely make readers think." — Booklist
