There's no one Kelsie Miller hates more than Eric Mulvaney Ortiz--the homecoming king, captain of the football team, and academic archrival in her hyper-competitive prep school. But after Kelsie's best friend, Brianna, moves across the country and stops speaking to her, she'll do anything, even talk to Eric, to find out why.

After they run into each other--literally--at the last high school party of the summer, Eric admits he's been ghosted by his girlfriend, Jessica. Kelsie tells him she's had zero contact from Briana since she left their upstate New York town.

Suddenly, a plan is formed: they'll go on a road trip to the University of Pennsylvania the following week when both Brianna and Jessica will be on campus. Together, they'll do whatever it takes to win back their exes.

What could go wrong?

Used to succeeding in everything, Kelsie and Eric assume they'll naturally figure out the details on the drive down. What they don't expect is that the person they actually need may be the one sitting next to them.
