I think this is going to be a fun, creepy, thrill ride with the usual tricks and treats. While the plot point of going to, and getting lost in, the catacombs is a unique intrigue, the rest of the story feels like it will be an easy, YA thriller read when you are looking for something quick to get the heart pumping. I'm looking forward to it. I'm hoping for As Above, So Below and Catacombs (2007 movie with Pink) vibes.
