Under the Surface

Ruby is afraid to give in to her feelings for Sean, worried he might break her heart, while Sean is excited to spend their senior trip in Paris with her and is willing to wait until she's ready for more.

When Ruby's best friend sneaks out to meet a mysterious French boy, Ruby follows with two classmates and gives in to another temptation, attending a secret party in the Paris catacombs. They never make it. Lost beneath the city as something sinister hunts them, they uncover dark secrets about the tunnels and each other, and must find a way out or die below. Aboveground, Sean searches desperately as news spreads about the four missing teens.
