The Fair Island — Anne Hampson

As different as possible in character from her identical twin, Alaine Marsland was persuaded to take Estelle's place on a cruise to the Greek islands. Away from the drudgery of her work, relaxing in the sun, enjoying the sightseeing, Alaine blossomed -- and learned that life could be beautiful. Cimon Duris, boarding the ship at Pireaus, added the perfect romance...

Then, along with the realization of her love for Cimon came an equally disturbing discovery. It was Estelle who had sown the seeds of the trouble -- but it was Alaine who was about to reap the harvest of revenge!

Hero: Cimon Duris
Heroine: Alaine Marsland
