Let me preface this by saying I suppose I have been jaded by reading Jennings' Aztec series...I just didn't find the pace or dialogue here as exciting.
There is obviously both deep research as well as thought put into this novel, and I respect what the author has created. It does fill in a "blank" in the period novels concerning this time and event- That of who the 2 men were that preceded Hernan Cortes in Mexico. (albeit by chance or mistake!)
I just never felt like I connected with any of the characters - I found myself rather loath to take sides! Actually, I think I identified more with Cortes than the primary character...He seemed less wooden to me.
It's worth a read by all means, but if you're looking for a faster pace, try Jennings.
