Kairo is a young boy marked by the loss of his father… until the day he discovers within himself a rare power: APEXGAMMA. A force unlike any other, capable of repelling the Thenneros, creatures from another world bent on destroying humanity.

As the world teeters on the edge of collapse, an unexpected encounter changes everything: one of the Thenneros betrays his own kind to help Kairo change Earth’s fate.

But will this unnatural alliance be enough to survive the coming war? Or will the cost of the truth be greater than the loss?
