by Ursus Ariston

Sent to Earth as scouts for a potential colony, three alien sisters are stranded on the planet for a thousand years. As they waited for rescue and repatriation, they thrived in the night world and secured daytime protection from generations of faithful men.

But the Sarmea siblings and their allies' idyllic way of life is upended when the 21st century dawned and they are hunted by transhumanist forces hell bent on exploiting the source of the extraterrestrials' immortality.

Book One in the series and the nanotechnology-enhanced vampire sisters and their intrepid lover-protectors from three continents face off a rogue corporation backed by the largest paramilitary machine a non-state entity had ever mustered. Hence, beneath the shadows of night, a secret war begins.
