Under the Surface

An epic survival-thriller about four teens lost in the Paris catacombs. Now in paperback!

"Tense and fast-moving, with a unique setting and compelling characters, Under the Surface is Diana Urban’s best yet."—Karen M. McManus, #1 New York Times bestselling author of One of Us Is Lying


Ruby is terrified to cave to her feelings for Sean and risk him crushing her heart.

Sean is pumped to spend a week with Ruby in Paris on their senior class trip, and he’ll wait however long until she’s ready to take things further.

When Ruby’s best friend sneaks out the first night to meet a mysterious French boy, Ruby goes after them as they head to an exclusive party in the Paris catacombs, the intricate web of tunnels beneath the city, home to six million long-dead Parisians. Only they never reach the party.

Underground, as something sinister chases them, they get lost in the endless maze of bones, uncovering dark secrets about the catacombs…..and each other. And if they can’t find a way out, they’ll die in the dark beneath the City of Light.

Aboveground, Sean races to find the girl he loves. But can he find her before it's too late?

From award-winning author and rising YA star Diana Urban comes a frantic, claustrophobic thriller set in one of the most intricate—and historically dark—places in the world.
