In 1390 England, Viviane is imprisoned for practicing witchcraft. Confident that the archbishop will believe her denial, she is stunned when she's led to the executioner without a hearing. Deeply disturbed by the young woman's fate, Sir Niall of Mallory grants Viviane's wish to hold her father's moonstone one last time. To his shock, the beautiful young woman disappears in a flash of bright light, leaving nothing but the moonstone behind.

Viviane finds herself on an island in British Columbia in 1999--but she believes that she's been transported to the legendary Avalon. Meanwhile, back in 1390, Niall swears to do his duty and recover Viviane. While retracing her actions, he triggers the moonstone and follows her across time. Unfortunately for Niall, Viviane happens to be onboard a boat and he lands in the water, his chain mail weighting him like an anchor. Rescued in the nick of time, Niall soon finds himself falling in love with Viviane, who believes that he's her knight in shining armor. The two lovers have a difficult path to happiness, however, for the evil archbishop has plans for them back in 1390 and they'll have to foil a dastardly plot and travel across time more than once in their struggle to live happily ever after. --Lois Faye Dyer
