In this thrilling second book of the Earthborn trilogy, Lucas and Asha have survived the decimation of Earth at the hands of the invading Xalans and seek safe haven with their enemy's true foes, the Sorans. They find a lush planet inhabited by a civilization far more advanced than their own, waging a seemingly endless war against a constantly evolving enemy. The Sorans call the pair of them the "Earthborn", and they're welcomed as heroes, almost as gods. To an audience of billions, they swear an oath to avenge their fallen planet by aiding the Sorans in their war against Xala.

But soon Lucas and Asha find Sora just as dangerous as apocalyptic Earth when they're targeted by the Fourth Order, a rebel collective who decries them as false prophets and harbingers of further bloodshed. Their friend and turncoat Xalan scientist, Alpha, believes he's located someone who can help them turn the tide of the war for good, stranded on a conquered colony planet. But landing on the new world, Lucas and Asha find themselves hunted by a violent, mysterious beast known only as the Desecrator, let loose by the Xalans.

Escaping Earth was only the beginning. As Lucas and Asha quickly learn, the universe has worlds and creatures far more dangerous than anything their home planet could have offered, and their continued survival hinges on gaining new allies they never could have imagined.
