Recently I read The Final Summit by Andy Andrews. The book takes up with David Ponder from The Traveler's Gift many years later. This is a hard to put down book like many of Andrew's other books. Andrews has a way of creating a picture for the reader and allows you to go inside the story. David Ponder is summoned, with 5 other travelers, to provide a two word answer to explain how humanity can get back on the right course. I highly recommend this book.
