A Drop of NightStefan Bachmann2016

Five gifted teenagers are selected out of hundreds of other candidates to fly to France and help with the excavation of a vast, underground palace buried a hundred feet below the suburbs of Paris. Built in the 1780's to hide an aristocratic family and a mad duke during the French Revolution, the palace was sealed after the aristocrats fled there. No one has set foot in it for over two centuries.

Now, in the present day, the teenagers enter with cutting-edge technology, state-of-the-art security, scientists and chaperones. And then a brutal accident occurs. No way out. Caught in the dark.

They will have to fight to survive. But are they really alone in the depths?
