Pangea, and almost back

In this time-traveling adventure, Freddie O'Toole is in search for his father, who has disappeared in a plane crash several years earlier. His guardian sends Freddie on a secret expedition to Timor where Freddie and his crusty manservant, Gruntenguile, are chased by Snapahuti headhunters. After a
narrow escape, they discover portals that take them back to Pangea and then to ancient Africa where Freddie becomes a contestant in the Tournament of Blood. He meets the leader of master aliens, the Zynes, who unlocks the secret of his missing father and a dastardly deal between the Zynes and the Axis Powers in World War Two.
Full-throttle dieselpunk adventure!
A wild adventure ride packed with non-stop action, intrigue, extraordinary creatures and memorable characters. Great fun!

What a sensational ride Pangea is . . . as it twists and turns, careers around wild unexpected corners from the very start, yet is consummately controlled by the invisible strings of [Henderson's] narration. I love the synthesis of every conceivable thing in the mix - hints of Lord of The Rings, Star Wars, epic classical heroes (á la Raiders of the Lost Ark), legends and myths, esoterica, science, para-science, geology, geography, anthropology, history, social iconography, bread and circuses, time travel and . . . Freddy!
