Rainbow Starr has spent years balancing school life, superhero duty, and a hopeless crush she’s finally worked up the courage to pursue. But on the one day she’s supposed to spend time with her long-time crush, disaster strikes—forcing her to choose between personal happiness and saving her city. In Steam Valley, a terrorist attack is being orchestrated at the central Train Station. The night before the incident, a local policeman uncovers the plot: a plan to sabotage the station’s control unit and derail a train carrying one of the city’s most influential figures, Max Freshline. However, before he can warn the public, he is ambushed, captured, and silenced. With no way to alert the authorities, he manages only one last desperate action—sending a warning to Steam Valley’s young superhero, Rainbow Starr. The message reveals more than just the attack itself. A highly advanced machine is leading the sabotage. Behind it stands a notorious villain whose agenda reaches deeper than simple destruction. Their target is deliberate: Max Freshline isn’t just a public figure—he is Bianca’s father. Bianca is Rainbow Starr’s civilian identity. Saving the train now means saving her own family. As Rainbow Starr races against time, she is forced into an impossible dilemma: Can she stop a derailed train, rescue her father, defeat a futuristic enemy, and still show up for the one date she has dreamed of for years? With the train speeding toward disaster and the city unaware of the danger, Rainbow must push her powers—and her heart—to their limits.
