I second this book too, it's a great introduction to Mesoamerican civilization. The author, Michael D. Coe, also has another excellent book "Breaking the Maya Code" on the decipherment of the Maya glyphs The fundamentals were done in 1950-60's by Knorozov and Proskouriakoff, but the decipherment was only widely accepted until as recently as the 1970's[1]!
