This series continues well as a team goes into a very ugly world to rescue a scientist and his latest invention. The United States prior to the 1940s was a very ugly place for a non white to exist and survive.

Much about the exploration of alternate worlds and the training required by the discovery teams. Ending with the challenge for one team to find its way home from the Mediterranean. A good start for this new and interesting series.

Disabled and crashed on a survey flight, the team makes its way home from the Mediterranean first by hand-made outrigger to N America then a skin canoe up the Mississippi. A death and injuries slow them down but on they trek.
