I found this book on Kindlenationdaily a few weeks ago as a free ebook. The story takes place four centuries in the future after a cataclysmic man made virus and then nuclear attacks. The Sword is an adult Christian fantasy with a good message about needing God both personally and as a society.
I enjoyed the characterization. The main characters were believable. Rather than all good or all bad, they possessed some of each. Society is defined by three secondary religions which are ruled by one supreme deity. All four religions seem to defer to man's baser instincts creating much of the conflict and tension. The Sword is the first book in a trilogy. Book two, The Gift, released this Spring, and the third book is due out next year.
