Witching Moon - K. E. Bonner - Bog

Every once in an eon, when the Earth eclipses the moon on a winter solstice, an immortal is born under a witching moon. Anne has always had the strangest feelings-memories she couldn't place; strangers she inexplicably yearned for. After she rescues the enigmatic Phillip from a shipwreck, her comfortable life on the island of Cusabo is shattered, and the mystery of her destiny starts to fall into place. Anne leaves behind the life she's always known and sets out with Phillip on an arduous journey to Amaranth, where her ancient family awaits her. But the path is dark and daunting, and Anne's powers have only just begun to manifest.
