At one point, Dr. Shepherd spends a few chapters reading a journal written in the 1930s by the daughter of the archaeologist who actually discovered the crystal skull on an expedition. I felt that section could have been written to summarize the journal entries rather than including several long, detailed entries in the text of the book. I was reminded of Mary Shelley's classic Frankenstein, which is written as a series of journal entries that I have never finished after multiple attempts. So this may be more my failing than that of the authors.
In another part of the book, Dr. Shepherd remembers how her daughter died in a choking accident involving a piece of candy. As a parent, the scene was almost too detailed and graphic to read without thinking about how I would react if faced with the same situation. It was one of the stronger scenes, yet somehow fit awkwardly into the grander scheme of things. Again, I feel it might have been edited a bit to smooth out this rough patch.
However, from the point where Laura enters the jungle in search of the Mayan temple where the crystal skull had been found 80 years ago, I felt more connected to the story. It was at that point that the authors' knowledge of Mayan history and architecture really shined through and the adventure kicked into high gear. From there to the end, it's a great thrill ride reminiscent of something you'd see in an Indiana Jones adventure.
Ultimately I enjoyed 2012: The Secret of the Crystal Skull by Morton and Thomas, but I wish it got going a bit faster than it did. If you're fascinated by the Mayan calendar, the impending date of December 21, 2012, and the mystery of the crystal skulls, be sure to check it out at your local bookstore.
