Destroyer - book 1

At the centre of a forbidden ruin, an artifact of black stone is unearthed.
Archaeologist Ru Delara, vilified by the scientific community for believing in magic, is summoned to investigate. When she arrives she finds herself inexorably drawn to the artifact and, unable to resist its pull, Ru reaches out to touch the stone...
Waking in the dark, naked and alone, Ru sees that everything and everyone within a mile radius has been vaporized. Only she and the artifact remain intact.
When a windswept stranger called Fen finds her, she has no choice but to accept his help.
Ru and Fen must unravel the secrets of the artifact before it falls into the wrong hands... before its darkness engulfs them all.
