I'm about 3/4ths of this book, and I highly recommend anyone to read it. But read my lips: skip the first chapters of Arawaks and Mayas. Michener, as a good 'american' thinks that those incredible people use to think as him... his descriptions of the character's thoughts are pitifully... american!
Besides some minor incoherences (in one page it's said that Drake always call this sea "The North Sea", and in the next one Drakes speaks about "the Caribbean"... I've been awake until 3 in the morning, reading. Few books had done this with me.
BTW, I'll try some other books of Michener, maybe even 'Mexico'. (I'm from there)...
