As a biochemist in 1908, Doctor Rosalind Werner has dedicated her life to the crusade against waterborne diseases. She is at the forefront of a groundbreaking technology that will change the way water is delivered to every household in the city–but only if she can get people to believe in her work.

Newly appointed Commissioner of Water for New York, Nicholas Drake is highly skeptical of Rosalind and her team’s techniques. When a brewing court case throws him into direct confrontation with her, he is surprised by his reaction to the lovely scientist. While Rosalind and Nick wage a private war against their own attraction, they stand firmly on opposite sides of a battle that will impact millions of lives.
