Sapiens Vampiris

Eleven years after the Purge — the war that nearly wiped vampires and therianthropes from the face of the Earth — humanity has grown careless. The exo-species, it is said, are gone.
They are not gone.
Amaneus Chad Bailan, 23, is the world's youngest doctor of exobiology and perhaps its most arrogant. With an IQ of 211 and a mind that refuses the supernatural, he has spent his career building a rational theory for the origin of vampires and therians — creatures his colleagues fear and misunderstand. For Aman, everything has an explanation. Everything can be known.
He is about to discover how wrong he is.
When a new Purge is declared and ancient forces begin to move in the shadows, Aman finds himself drawn into a world far older and stranger than any scientific model can contain. Alongside a 700-year-old Florentine vampire, a fearless adoptive mother with lethal secrets, and a weretiger he cannot stop loving, he must navigate warring immortal factions, a conspiracy reaching back to the very first creatures ever to walk the Earth — and the truth about his own blood.
Sapiens-Vampiris is a breathless, idea-driven sci-fi thriller set between Dakar, the Arctic, and Addis Ababa — a novel about the arrogance of reason, the cost of love, and what it means to be human in a world that was never entirely yours.
