Devil in the DeviceDevil in the Device

Battling the dangerous forces buried within their minds, Andra and Zhade will have to find a way to work together before two power-hungry leaders and a deadly swarm of rogue technology destroy humanity for good.
Zhade is still getting used to wearing Maret's face, but he can't deny that the influence it affords him has its perks. When the magic of Eerensed starts to turn deadly, Zhade must master the Crown if he is going to save his people, and Tsurina's destructive plans for Eerensed aren't going to make that easy. Assumed dead by the people of Eerensed, Andra must stay underground if she is going to live long enough to build the rocket that will finally save the colonists from this dying planet. When she hears voices urging her to destroy everything, Andrea begins to question whether she is destined to be a savior after all. -- adapted from jacket
