Meet the crew
One brother who would rather be home, one sister who has to know everything, and one dog who's ready for anything. Together, they've found a way to travel through time.
Ethan wanted a normal summer with friends, Wi-Fi, and video games. Instead he got a creaky farmhouse, a cave, and a T. rex.

Who built it? Why was it hidden in Pennsylvania? And why are there glowing points all over its map of the Earth? The answers unfold across the whole saga.
