Caped and Dangerous by Isabel Jordan

Being a superhero is not all it’s cracked up to be
Saving the day is sometimes the last thing Greer Glenanne wants to do. But as her city’s official superhero, she really doesn’t have much of a choice. It doesn’t matter that she’s forty-six, grumpy, and annoyed by most of the population. She’ll catch whatever criminals she needs to catch because that’s the gig. Next up on her to-catch list?
Killian Morgan.
He’s stupid-hot, way too charming for her liking, a decade younger than her, potentially a supervillain…and he flirts with her mercilessly.
How’s a superhero supposed to do her job when she can’t seem to keep her mind (and hands) off the bad guy?
