Five hidden engines. One ancient guardian. A collapsing timeline.

Deep within an Andean caldera, sixteen-year-old Lena and her friends awaken an ancient network of precursor technology, capable of bending time itself. Guided by Kaelen, the last saurian chronicler, they discover Earth’s planetary grid is failing. To stop the collapse, the trio must race across six historic eras—mastering forgotten science before the timeline unravels forever. Repair the past, or lose tomorrow.
