Stedfast is a guardian angel, assigned to various people throughout time to watch over them during their last hours/days of their lives. He narrates each persons losses and triumphs to the reader. This one is not so heavy on the sin future as much as it is with redemption. The last part of this book involves the rapture.
Unlike the angels of the previous books of the series, Steadfast was true to his name. The guardian angel assigned to the very first man, Adam, he stays faithful to God, and gives an angel's eye overview of history and eternity. An interesting book, meant to make the reader think.
