It’s Senior Week, that magical in-between time after classes have ended but before graduation, chock-full of gimmicky theme parties, last-minute bonding, and family traditions. Olivia couldn’t be more ready. Class salutatorian and confident in her future at LSU, she’s poised to sail through to the next phase of her life.

But when the tiny hiccup of an unsigned off-campus P.E. form puts Olivia in danger of not graduating at all, she has one week to set things straight without tipping off her very big and very nosy extended family. Volunteering to help at a local golf tournament should do it, but since Olivia’s mom equipped her phone with a tracking app, there’ll be no hiding the fact that she’s at the golf course instead of all the graduation parties happening at the same time. Unless, that is, she can convince the Fab Four–her ride-or-die cousins and best friends Sophie, Charlie, and Wes–to trade phones with her as they go through the motions of playing Olivia for the week.

Sure, certain members of the golf team are none too pleased with Olivia’s sudden “passion” for the game. And sure, a very cute, very off-limits boy keeps popping up in Olivia’s orbit. But she is focused! She has a schedule and a plan! Nothing can possibly go wrong . . . right?
