Return of The One. Return of the One Trilogy, #3

In book three of the Return of the One trilogy, follow the Three, Vid, Bec and Cee, as they raise up an army and wage battle after battle.  This is what they have been told is their destiny to prepare for the Return of The One.  However, they do not know when He will return?  Are the Three ready to lead?  Will they survive? Others are helping them to prepare for the ultimate battle with the Servants.  But first, they need to get the women and children to safety.  Towns need to be vacated.  A place needs to be found for building an army and planning.  Is there enough time? Smaller battles are going well.  However, is the General of the evil forces just playing with them?  Is he evaluating their tendencies and tactics for the larger battle?  Does he have a spy in their midst? The circle of friends around the Three continues to grow.  It seems the Given are not the only ones wanting to see the Servants defeated.  Friends come in various forms. Victory hinges, however, on the Return of the One.
 How long do they wait?  Time is of the essence.
