I actually started this way back in September of 2009, but it's kind of huge. It literally starts with the cooling of the earth's crust, so it takes a while to get through. I thought I would be finished before we went to Kauai in November, or at least would finish while we were there, but it wasn't even close.
Really good, though. It gives an interesting overview -- in fictionalized form -- of the politics of the islands.
