There isn't really a whole lot of hunting for Atlantis in long parts of this book, it is more like a series of action scenes, some of which are better than others. I agree with others in that the main characters of Wilde and Chase were a bit shallow and lacked credibility.
That being said, it is a fast moving easy read which is very entertaining in parts, especially the under water scene, so I'd say that while this isn't fantastic it is an enjoyable read. Fans of Matthew Reilly and James Rollins should enjoy, just maybe not as much.
