Synopsis by Cammila Collar
Flint and his father lived in the prehistoric era, where they were frozen. Now, in contemporary times, they've been thawed out and brought back, but they awaken to horrible news: a dark lord has traveled through time, leaving special devices littered throughout history that could change the course of the future if they aren't found and stopped. Now Flint and his father, along with their friends Sara and Tony, are in for a time-traveling adventure without a second to lose.
