Query: Nutty Theories

This book is fun for people who want to read a work of total fiction. However, for people who care about accuracy it is full of misinformation that does a disservice to readers who don't know any better. The sad thing is that there is good data out there, lots of it, especially on the Maya see Linda Schele's and David Fredel's "Maya Cosmos" and Barbara Tedlock's "Time and the Highland Maya," for example. Why do people who should know better write such stuff? And, perhaps more importantly why does anyone publish it?
