A Ramtalan Trilogy — Sofia Diana Gabel

The third and final book in the Ramtalan Trilogy brings Argus and Tai Dachel to a critical juncture in their lives. Struggling to maintain some sort of normalcy, the boys soon discover that they'll never be the same and those around them, including Argus's girlfriend Lola, are in danger from the Invaders and the government agency AURA. With enhanced abilities, Argus has to come to grips with being different from his brother, and being an enemy to the Ramtalans he thought were his friends. When hyper-intelligent, powerful Argustine Lenox and his sister, Galena, threaten to cleanse the Earth of humans and New Breeds, Argus and Tai have a difficult decision to make. Which side do they join? The Invaders accept him, while the Settler Ramtalans consider him dangerous. As if that's not enough, Argus is on the brink of adulthood and must choose what sort of man he wants to be; defiant, compassionate, strong or all three. Nothing will matter though if he can't save the Earth.
