Query: Very good

I heartily enjoyed and highly recommend this book. As someone else suggested, one should also read the 1st person account of Bernal Diaz, maybe before or maybe after this book. After reading this book, I looked for other works by Hugh Thomas, and found his book on Cuba. Now that was a monster, rather difficult to read, but very good history written to the very high academic and intellectual standards of Britain (just like this book on Cortes).
