Bradley Graeme is pretty much perfect. He's a star football player, manages his OCD well (enough), and comes out on top in all his classes... except the ones he shares with his ex-best friend, Celine. Celine Bangura is conspiracy-theory-obsessed. Social media followers eat up her takes on everything from UFOs to holiday overconsumption -- yet, she's still not cool enough for the popular kids' table. Which is why Brad abandoned her for the in-crowd years ago. (At least, that's how Celine sees it.) These days, there's nothing between them other than petty insults and academic rivalry. So when Celine signs up for a survival course in the woods, she's surprised to find Brad right beside her. Forced to work as a team for the chance to win a grand prize, these two teens must trudge through not just mud and dirt but their messy past. And as this adventure brings them closer together, they begin to remember the good bits of their history. But has too much time passed... or just enough to spark a whole new kind of relationship?
