The White Witch
Indiana Jones and the White Witch is the eighth of twelve Indiana Jones books published in the 1990s. This series, officially licensed by Lucasfilm, is inspired by the Indiana Jones character who first appeared in 1981 with the movie Raiders of the Lost Ark. Rob MacGregor authored the first six books. Martin Caidin wrote the seventh and eighth books including The White Witch. Max McCoy wrote the last four books of the series.
The events of this adventure take place in 1930. Indiana Jones teams up with Gale Parker (a woman aviator introduced in The Sky Pirates) and Caitlin St. Brendan (the White Witch who practices the religion of Wicca) to prevent Konstantin Cordas from capturing a collection of gold coins dating back to the time of Christ. The story opens in the New Forest in southern England. Subsequent events take place in London, Germany, the Graf Zeppelin as it travels across the Atlantic, and Florida.
This is one of the better books in the series. Caidin further develops the relationship between Gale Parker and Indiana Jones; though not romantic nor intimate, Indy and Gale have a strong friendship based on trust and respect. Caidin also brings aviation history into the story as the Graf Zeppelin and the S-38 Sikorsky flying boat are very much part of the adventure. Finally, I like how Caidin skillfully brings Arthurian legend, the religion of Wicca, Stonehenge, and the American Civil War together to make for an interesting adventure story in keeping with the Indiana Jones tradition.
