To Lady Isobel Macleod, marriage is a prison and husbands irritating encumbrances. Her domineering father and ferocious brother-in-law have proven as much to her. But when she comes upon Sir Michael St. Clair, master of Rosslyn Castle, being beaten by vicious strangers, she flies to the knight's defense, helps him escape, and flees with him into the rugged Highlands and beyond to the misty Isles. Alone under the stars with the man whose gaze holds her spellbound, Isobel ponders her long-held prejudices. But as their relentless enemy pursues them, she faces a new danger-surrendering her freedom to this fearless yet tender man - and linking her fate forever to the treasure that stirs mankind's greed and imagination to this very day.
