Based on Principal by Marie Johnston

Nothing good happens when she takes her mask off.
By day, Natalia is the strict principal of a private school with a staid, troubled legacy. By night, she’s a lithe, agile assassin with a penchant for latex. Or at least her cosplay character is. The two identities don’t mingle until she meets a handsome comic book shop owner at the local comic con. Now there’s a guy she’d be willing to peel her mask off for.

Too bad he’s the father of one of her students.
Single father Chris has no time to date, thanks to his business, his daughter, and his ex’s meddling family. But how can he resist a comic lover in a business skirt? She’s his perfect woman. Or she would be, if she didn’t keep the professional and play parts of her life so separate. And he swore he’d never date a woman ashamed of him again.

Too bad she’s obsessed with what the wrong people think of her.
Together, they could be an unstoppable duo, but when Chris’s daughter acts out at school, Natalia will be put in an impossible position: break all her school’s rules, or pack away her cape forever.
