Say Uncle by Raquel Riley

A bratty middle meets his match in his strict step-uncle when he pushes all the wrong buttons.

Samson
There were other ways I could’ve spent my summer, but my sister’s stepson needed a swift kick in the rear and she thought I was the perfect man for the job. I’m no brat tamer, so being saddled with one wasn’t my idea of a good time, but I can see the appeal when my… less-than-conventional methods prove fruitful.

Matteo
Sam is an egotistical, cocky, rude, impatient jerk. He’s also my boss for the summer… and my stepmom’s brother—did I mention he’s hot AF? He’s supposed to be teaching me a lesson about becoming a man and respecting authority, but his methods probably aren’t what my parents had in mind.
