Some Kind of Hero (A Hesitant Hero Book 2)

Kayo's back and kicking ass.
It's been a hard six months since Karen Hashimoto quit being Crushette – number one henchwoman of Doctor Maniac and super-villain extraordinaire – and became Kayo, member of the superhero group, The Good Guys.
After winning a candidacy for the most prestigious award possible, Kayo's not-so-far-gone past comes back full-swing, determined to show the world that changing the name doesn't really change the girl.
Facing off against friends, foes, and everyone in between, Karen must prove once and for all that she truly is some kind of hero.
