Emma Robledo has a few more responsibilities than the usual high school senior, but then again, she and her friends have left school to lead a fractured Resistance movement against a corrupt Heroes League of Heroes. Emma is the only member of a supercharged team without powers, and she isn't always taken seriously. A natural leader, Emma is determined to win this battle, and when that's done, get back to school. As the Resistance moves to challenge the League, Emma realizes where her place is in this fight: at the front.
