Kairos Astroire & the Snowdrifts (Gaia's Secret Book 1)

The gods had forsaken the mortals and returned to their celestial realm. The eight supreme beings that were once revered became names that no one recognised until someone who is destined to replace one of the supreme ones appeared and the world once again trembled for the chaos that was about to return. Kairos is born in Saint Empire, a land of permanent spring that is as dangerous as it is beautiful.

Living in a warring state, he was enrolled in the military academy along with his playmates, but as poor village boys, they are always at the bottom rung and soon face expulsion and a life of poverty. However, everything changed when Kairos discovered an unbelievable inheritance in an old musty manuscript, and the doors that were meant to be closed were blown apart. They still have one last chance if they could excel on a mock battlefield, but the greed of man brought back an ancient foe of humanity, and this simple examination became a mad struggle to survive.
