Cities vanished, gone in flashes of world-shattering destruction. An alien race had come to make Earth theirs, bringing a power so far beyond human technology it seemed like magic. It was nearly the end of the world--until we learned to seize the power, and use it to fight back.
The war has raged for five centuries. For a cadet like Jax, one of the few who can harness the enemy's universe-altering force, that means growing up in an elite military academy, training for battle at the front--and hoping he is ready. For Naomi, young nomad roaming the wilds of a ruined Earth, it means a daily fight for survival against the savage raiders who threaten her caravan.
When a new attack looms, these two young warriors find their paths suddenly intertwined. Together with a gifted but reckless military commander, a factory worker drafted as cannon fodder, a wild and beautiful gunfighter, and a brilliant scientist with nothing to lose--they must find a way to turn back the coming invasion, or see their home finally and completely destroyed.
