Publisher's Summary

In this extraordinary adventure story, Billy Bartram, his father, and a secret society of philosophers and scientists venture into the American wilderness in search of the lost people of the Welsh prince Madoc. Traveling in a flying airship, the members of the expedition and Billy face hazards greater than he can ever imagine as, together with his father, he gets caught up in the fight for the biggest prize of all: America.

Better in a faster speed.

The voice was somewhat dull, but on double speed, the story was much more lively and realistic.
