Puzzle, the second novel in Stephanie Powell's futuristic and dystopian YA series, is just as compelling as its predecessor. As Powell leads readers on Cassie's journey to find Sam, she introduces fascinating characters: the mysterious Virginia, the now six-year-old Cody, and a cast of menacing mecs, for starters. The author crafts a truly unexpected story--I was unable to put Puzzle down--and creates palpable tension and suspense throughout the novel. Powell also balances her dialogue with humor and tenderness, creating characters that feel genuine. Fans of sci-fi, dystopian novels, and futuristic fiction will love Powell's work. After finishing Puzzle, I was eager to read the final book in the Pink trilogy!
