This novel took me by surprise.
On the surface, it really looks like a kid's book. It is short (not even 200 pages), published by Scholastic, and the Nazi on the cover looks like a comic book character (metallic arm holding a ball of electricity). Nevertheless, the writing is excellent.
The book is stripped of all unnecessary thoughts and inactivity. The author filled the book with foreign language, World War II research, and impressive scholarship.
I really kind of expected something more shallow, and still hoped that it would be enjoyable. I found instead a novel that was endlessly intriguing (I mean, we zip from Mayan South America, to the house of Henry Jones Sr. in the US, to Fascist Italy during World War II, to the Middle East). Characters are speaking in Spanish, Italian, and German all over the place--and that's what I remember off hand.
To anyone who really loves Indiana Jones, no matter your age, I promise you this is an enjoyable read, no matter how short. I can only wish that the author will consider writing more Indy novels. I mean it.
