Harley Quinn Reckoning (DC Icons Series) by Rachael Allen

In this new launch of a trilogy within the DC Icons universe, experience the origin story of a Super-Villain. This is the Harley Quinn backstory fans have been waiting for.
 
When Harleen Quinzel scores an internship in a psych lab at Gotham University, she's more than ecstatic; she's desperate to make a Big Scientific Discovery that will land her a full-ride college scholarship and get her away from her abusive father. But when Harleen witnesses the way women are treated across STEM departments—and experiences harassment herself—she decides that revenge and justice are more important than her own dreams.
