Beyond the firewall lies a greater threat than Taimin and Selena could have foreseen.
Taimin and Selena have destroyed the firewall that once trapped them in their dangerous wasteland. But with their hard-fought freedom now comes a greater threat.
Outside the wasteland, under the same two scorching suns, live the bonded. This powerful ancient enemy will unleash a destructive war on the wasteland's inhabitants, and Taimin knows it's a fight they cannot win.
When Zorn comes under attack, Selena uses all her power as a mystic to protect the white city. Meanwhile Taimin's path takes him to Agravida, the capital of the advanced bonded civilization-where he must work fast to find a weakness in a seemingly unbeatable enemy.
To save everyone in the wasteland from certain death, Taimin and Selena seek to contact their ancestors in the stars. But will they reach them in time, and will their help be enough to turn the tide? The existence of the world is in their hands.
