The Mantis Variant by Adam Andrews Johnson

In the dark future of our world, a small percentage of humanity has evolved with a physiological anomaly that provides them with wondrous abilities. Those gifted few are now targets of the unevolved, looking to steal that power. "The Mantis Variant" follows Agrell, Dozi, and Ilya together in the rundown metropolis of Teshon City. The unlikely trio is set on a path of unexpected heroism through horrifying trials that lead them to sacrifice and redemption. Their group increases throughout the story, and for some, the harrowing events bring growth. However, bizarre eldritch rituals and arcane arts are commonplace in the world of "The Mantis Variant," and tragedy and death are always close at hand.
