County Donegal, Ireland, 1597 AD
Millennia have passed since the glaciers receded. Civilizations have risen and fallen many times in the interim, and all trace of the Age of Miracles has been lost to time.
Connor had been plagued by vivid dreams, sometimes eerily prophetic, for as long as he could remember. He has led a sheltered but lonely life under the protection of Donegal Abbey, until the arrival of a handsome and charismatic stranger, come to study at the monastery's library.
Ruarc, a low-ranking Nightwalker of House Diluthical, has been chosen to infiltrate the Donegal community, following rumors of a young man touched by Second Sight. His mission takes a dangerous turn, however, when he encounters a legendary creature of immense power and unknown intent, who has walked the earth for all of recorded history, a mystery hiding in plain sight.
