There's no description on here, so here's the back cover blurb.
A luxury cruise through the Mediterranean - starlit nights and sun-drenched days. The perfect setting for romance, Janine thought. But what did it matter to her? Long ago she vowed never to trust a man again. Then she met Alexandros Sakotos, and thought he knowingly deceived her, Janine could not keep him out of her thoughts. The dark, commanding Greek seemed to possess some secret power over her, some special sympathy of feeling and thought. When he asked her to pose as his wife before his family and friends, Janine had no choice but to grant him her faith and trust . . . After all, she sadly realized, she had already given him her heart.
