Altered: The Alpha Children
Psi is perfectly content with hiding away in his little corner at the bottom of the world. He is an Alpha Child, subject to intense esoteric experiments that granted him supernatural abilities and taught to believe the world was hostile. He has very little desire to return to the past he escaped from.
When Sigma, another Alpha Child, tracks him down, she brings his past with her. Finding himself dragged back into the world he left behind, he must find and convince the remaining Alpha Children to help them fight back against the Order that created them.
Altered is a series of short stories following Psi and Sigma as they travel around the world finding the other Alpha Children. Each short is a self contained narrative, with the whole serial having an overarching plot.
