Blood is all there is. The Vita is all that gives.

When the High Monarch takes his own life, the Senvia Empire plunges into chaos, while Civil War stirs beneath the collapse of order.
Far from the now-empty throne, Blanc of Blood Denegis has no interest in politics. He hunts, he trains, and quietly strengthens the Raw Vita within him, the fate of every second son of Noble Blood.
But mere days after the Empire begins to fracture, the ripples reach even his Blood.
Suddenly, he finds his Blood the victim of an approaching traitorous army, rising tensions, and paths that the Vita Herself seems determined to place before him.
To protect his younger siblings, Blanc must step forward. To survive what’s coming, he must get stronger, harvest more Raw Vita, and learn the true cost of sacrifice. And as the world begins to notice this second son of Blood Denegis, one truth becomes clear:
When the old order dies, new Blood must answer.
