Four of Hearts — Marsha Manning

The ancient city of Beirut with its hot sun and its blue sea was far removed from cold, damp London. To Sandra and Jill, who were tired of working in England and in a mad moment signed a contract to work for two years in the Middle East. it was a city of enchantment. And the two attractive men they had met on the plane coming over--members of the Fallowman expedition which was searching for artifacts in the desert--spelled romance as well.

Then they suddenly lost their coveted position and had to appeal to their new found friends to secure them positions with the expedition.

A tender love story set against an exotic and fascinating background.
