Just finished reading this one, and I give it a solid 8 out of 10. I thoroughly enjoyed reading it. Characterizations were very good. Young Indy is driven by his desire to become an archeologist. In addition, we see his interact with an influential woman in his life. He learns from her to be true to himself, to go after his goal, and do what is right for him.
I thought the background information was solid. I did a little online research on the true Oracle at delphi, and MacGregor does a great job weaving this mythical legend into a believable Indy adventure. Indy is not traipsing through the jungle, searching for an artifact. Instead he is truly "coming of age" discovering himself and becoming comfortable in his own skin.
I liked the depth of character that MacGregor gives Indy. And I liked the comraderies of Jack Shannon and Conrad. And I enjoyed the hero worship that Nikos brought to the story. All in all, this is a very satisfying read. I see it fitting well into the Indy timeline, and it helps us understand the development of the character.
Why not a 10? I got the feeling the author was holding back a little, maybe hesitant to make the character more his own. I think this will improve in the future volumes.
I remember starting this one, and reading to a certain point. However, I think this was my first trip all the way through. It was a glorious ride, and I'm looking forward to starting "Dance of the Giants".
Get this book... It's fun, good story telling, and another peek into the archeologist's history.
