Fight Crime! (A Love Story) by Kristen Brand

David Del Toro just wants to make the world a better place. It would be nice if he could find a way to do that without punching people, but as the superhero White Knight, that’s kind of in the job description.

Valentina Belmonte has one small, simple goal: to be the greatest supervillain who ever lived. Unfortunately, meddlesome heroes and her own backstabbing allies aren’t exactly making that goal easy to achieve

The two of them really shouldn’t fall for each other. But even with incredible superpowers, they just can’t fight true love. Yet if they want to survive long enough to be together, they’ll have to battle invisible assassins, their own personal failings, and a power-hungry crime lord who can kill with a single touch.
