Seventeen years ago, contaminated water runoff from a chemical plant caused deaths and birth defects throughout the small town of Bourne. One Two Three tells the story of sixteen-year-old triplets: Mirabel, a genius trapped in a wheelchair using a computer to speak; Monday, a neurodivergent bookworm; and Mab, who feels guilty for being "normal." When the company decides to reopen the chemical plant, the sisters become obsessed with finding the necessary proof to stop them with the help of the owner's grandson who just moved to town.

I have mixed feelings about One Two Three. The highlight of the book was the Mitchell sisters, with chapters cycling between the three, each with a distinct voice. The interplay between the sisters fascinated me and I loved seeing how their actions and abilities affected each other. Yet, the evil corporation storyline was a bit trite and the second half of the book was overly long and repetitive.
