The Crystal Tower

Caleb Stone has been Serumina's Galactic Peacekeeper for over a hundred years. With Sam Davis at his side, it's a position not as demanding as he thought it would be.
He has let his guard down. On the far side of the galaxy, hidden behind the Core, an old enemy crosses his path. Is there someone else behind the evil motives, or is this an isolated problem? While dealing with this, Caleb's personal life takes a most unwelcome and life-altering turn.
Meanwhile, there is a ripple, a tremor, in the heavens as one of the Ancient Ones prepares to alter his own destiny and the Peacekeeper stands in his way. With the Fate of the Galaxy in his hands, Caleb is forced to face this unexpected enemy armed only with his grit and determination. Closest friendships and alliances are tested until he doesn't know who he can trust, he begins to doubt his own ability to deal with this, and his persistence to do the right thing is taken the ultimate end.
Can the little orphan boy from Arizona outwit one of the most formidable foes of all time?
