Dr. Shamus Bergin and his former patient Erladoch Dunbar have leapt into a time portal hurtling them backwards 20,000 years to Loura, a time and place erased from history. Before the seas rose up to separate Ireland and the British Isles from the rest of Europe, the Kingdoms of Loura thrived in peace.

Much has changed since Erladoch's departure four years earlier. Enilorac, the Evil King of Treborg has already begun his invasion. He has come looking for the last Angel's Itavo stone. If found, Enilorac will use it to open the gates of Hell and usher in the end of times.

Having accepted that his parents were descended from the Sacred Order of Keepers, Shamus must find his place amongst this army of part-human, part-angel warriors in their struggle to repel the encroaching darkness. Can this man of science come to terms with a world filled with magic, or will he lose his sanity in the presence of so many emerging voices seeking to direct his Will? These voices, whispers from the past and echoes of future battles, threaten to overwhelm him.

Burdened with so much, the answers he seeks may lie in the hands of a woman he has never met. He doesn't know her, but her call grows stronger in his mind with every passing danger. With the weight of obligation crushing down on him, he must have faith that his allegiances will hold and that not all paths laid before him will ultimately yield the same destiny.
