What it’s about
A huge burrowing machine tunnels out of control at ferocious speed, cutting clean through to the center of the earth, to the twilight world of pellucidar. Once there, Dr. Perry and David Innes are threatened by half human creatures, lizard-like birds, and man-eating plants.
If your child is sensitive
If they get scared: under 7, a cuddle or a pause helps more than explaining it isn’t real. From 8, explaining does work.
