Birthright (The Impavidus Cycle, #1)

MY CHILDREN WILL KNOW PEACE AGAIN.
When a young daemon becomes host to his father, the eons-old progenitor of his kind, it seems his only purpose is to kill and kill again, to build a new world fit for the dark to rule. Unseen by humans, the world has long been controlled by the strings of a shadowy secret society of immortal beings, the Order of Azoth. As the organization fractures and begins to unravel, he may be the last hope of the Order to quell the spread of corruption and change the path of the future. Just as they may be his only hope to discover his own humanity.
"Vice has struck a perfect equilibrium between darkness and tenderness in this slow, introspective dark political fantasy. If you're seeking out grimdark settings in the vein of BERSERK and ELDEN RING where love blossoms in spite of insurmountable hardship, then look no further."
— Camilla Andrew, author of WHEN THE STARS ALIGHT
THE IMPAVIDUS CYCLE is a dark historical fantasy about identity, family, and finding yourself, set in the rich historical backdrop of the renaissance.
WHAT REVIEWS ARE SAYING...
"A stellar example of independent authorship, a slow-burn plot that goes to extremes but embraces its warmth, and a well-realized world with an absolutely killer intro and an even more awesome conclusion, I can highly suggest BIRTHRIGHT to anyone interested."
"A wonderful series start, giving enough to stay with you—but still making it very clear there's a vast and dark world still yet to be shown."
"The way Vice is able to capture the intricacies of growing and changing relationships between between the characters is stunning. The protagonists are not only characters you want to root for, but characters that you will come to love and hope the best for."
