Swear by Apollo — Shirley Barker

The Scottish island of Rona, deep in the Hebrides, had never seen a doctor before the handsome blond Yankee arrived.

For young doctor Randall Woodbury, fresh from the rebellion-torn hills of New Hampshire Colony, Rona was an isle of strange wonders -- where his concepts of science were challenged by ancient magic, where secret potions brought the dying back to life and an old woman practiced chilling powers of divination.

There, he lost his heart to the beautiful Margery Rhinn -- but to win her he faced a nightmare ordeal that threatened his career, his honor, and his life.
