The Diamond of Freedom, book three in The Unaltered, melds together history, geology, metaphysics, science, and fantasy in this non-stop nail biter. Calli and Chris race against the clock to identify the power-neutralizing stone that prevents Calli from healing her life-threatening injuries. She must also learn how to counter its effects before she can fight against the rogue Diamond Bearer named Freedom to save the boy she loves and the world of her friends.
In the epic battle between extreme cosmic-power holders, weaknesses are exploited and lifetime relationships shattered to gain the upper-hand. Sometimes having no special abilities is what makes someone the most powerful. General Harding, Chris's father, has made it his life's mission to eradicate all people with powers. Believing the lies fed to him, and misusing his status with the U.S. government, General Harding nears completion of a weapon designed to destroy cosmic-energy individuals.
Calli meets Brand Safferson's half-sister, self-named Deus Ex, and proclaimed mercenary. Her repeating abilities are necessary to rescue Brand from General Harding's compound, but the risks of recruiting her to abandon Freedom's side and join Maetha's may be deadly.
