The Atlantis Code isn't bad for a kind of Indiana Jones wannabe. The story is interesting and exciting, the characters are, for the most part, believable. The only exception to this is the protagonist, Thomas Lourds. Though I actually did like his character, he's a bit of a Mary Sue. He's incredibly intelligent, good looking, and capable in every way, although he's an academic. Personally, I don't know any academics who are also handsome millionaires. Even Indiana Jones, handsome, charming, and capable, was no millionaire, and failed in many of the things he tried. Lourds doesn't. He's able to solve every problem he faces with little difficulty. And he beds BOTH of the female main characters without even trying. He's just that good. I also didn't appreciate the very erotic sex scene in the middle of the book. Some people like that kind of thing. I don't.
Overall, though, this book was interesting and entertaining, and that's all I ask for.
