If you want to read about the conquest of the Incas, one of the two biggest epic stories in the Americas (the other being Cortes' conquest of the Aztecs, then you really only have two choices: John Hemming's The Conquest of the Incas, and Kim MacQuarrie's The Last Days of the Incas. Hemming's book was published in 1970, thus recent discoveries in Peru during the last four decades are missing--and a lot has happened. It is a very detailed book with lots of footnotes and research, however, it was written by an academic and is average in writing quality. There is thus no attempt in Hemming's book to bring the characters to life, or even to tell their full stories. MacQuarrie's book, on the other hand, was published in 2007 and thus is very up-to-date. You'll learn about recent and important discoveries in 1999 and 2001, how Machu Picchu figured into the conquest and was discovered, and so on. But what really sets it apart from any other book on Inca history is the writing quality. The Last Days of the Incas is really a phenomenal read, the best that I've come across, period. Not since William Prescott's The Conquest of Peru (published in 1847 and a big best seller in its time, but now very outdated) has anyone achieved what MacQuarrie has achieved, bringing the conquest of the Incas back to life. The Last Days of the Incas is not only well researched and up-to-date, but the book is an amazing page-turner. Once you pick it up, you won't be able to put it down. The author really succeeds in recreating Pizarro and his conquistadors and the various Inca emperors as full, three-dimensional characters. In sum, if you want to transport yourself in a time machine back to the 16th century in Peru and feel what it was like to be a participant in the sprawling epic that was the conquest of the Inca civilization, there's only one book to get: The Last Days of the Incas. Its a real tour de force.
