Darkness of the Blood

The Autobot-Decepticon War reaches its climax as a new, dangerous adversary enters the field, and an unforgivable crime is committed. A crime that Jack cannot forget. Now once again he must take part in a war that is now his, watching the world around him fall apart. If he is to save all he loves, he must come to a realization: the War must end, or Unicron will destroy them all.
