Book six of The Unaltered. Calli is assigned to help rescue imprisoned scientists from a facility eerily similar to General Harding's. Even with Brand's help, this will prove to be difficult at best. The task reveals a new, man-made, power-removing substance.
Another threat still hanging in the balance is Max Corvus and the obsidian bullets he now possesses. Calli's first major failure as a Bearer will ignite a bidding war for the information Max has about her and the others.
If these two new powerful weapons weren't enough to worry about, Calli also discovers a plot among her own group once Chris decides to become a full diamond bearer. With her own future at stake, Calli must change the rules that have always been laid out for her.
Sometimes, discovering one's purpose in life can be a letdown. Or, it can cause one to rise up and fight back.
