Ever Upward - The Excelsior Journey, #2

An ancient foe. A divided planet. An impossible choice to make. A newly established link between Denab IV and Earth has endangered both planets, causing Excelsior's own people to turn against him. With General Hodera ready to lead a deadly new army and an ancient foe awakened and more powerful than ever, everything both Matthew Peters and Excelsior love is on the brink of destruction. Excelsior must return to Earth to undo the damage he has caused to his planet and his people, but doing so would sever the connection Matthew Peters still has with his loved ones. A decision must be made, but time is running out.
