I loved this book. I thought it was even better than Dan Brown - a gripping thrilling read, exceptional. Actually it was a bit like 'Indiana Jones meets the Da Vinci Code' but far more thought-provoking, sensitive and intelligent than either of these. It's basically an archaeological detective story and a dark supernatural thriller about what might happen at the end of this year if the ancient Mayan prophecies turn out to be true.
I also understand from an interview with the authors I just read in Exclusive Magazine .com that this novel actually began life as a screenplay which inspired both the Indiana Jones movie about crystal skulls and the Roland Emmerich movie about 2012, but this book is actually far better than either of these films. It's a great story so read it and enjoy!
