Dr. James Sylaindur has vanished after hijacking the Large Hadron Collider to test his theory of the Infinity Wheel - that our universe consists of nine intertwined realities hidden among the extra dimensions of string theory. Determined to save their father, teens Jessanda and Tevan, along with their mother Natalie, attempt a poorly planned rescue operation by translating themselves to a parallel reality. Emerging on the beautiful tropical planet Ka'sora, the family is imprisoned by the Felidais Papalia - primitive yet intelligent cat-aliens who abhor technology in favor of grei'ca, their physics-defying ability to manipulate matter and energy with thoughts alone. Desperate to find favor with their captors, the Sylaindurs pretend to be envoys come to deliver a message of great importance from the Felidais gods. But the arrival of technology-using strangers claiming holy knowledge explodes into a Felidais tribal civil war, putting the family in even greater danger. Pursued by belligerent Ther'rendo and his Fighters, five brave Felidais escort the Sylaindurs on an adventure-packed journey to consult their most revered leader, the Tree Guardian. The family must ally with their Felidais captors in a climactic battle among the ancient relics hidden in the Tree Temple, where the Sylaindurs and natives stumble upon the astounding history connecting Humanity, Felidais, Earth, and Ka'sora.
