Troubled Waters — Susan Sallis

Liz McGregor, struggling to bring up her eight-year-old daughter alone, is surprised when her boss asks her to marry him. It is an unromantic proposal, but Liz, beset with difficulties, is tempted to accept it. Then Felix suggests a honeymoon cruise in the Adriatic and Liz's fears are swept away.

After eight empty years she is loved - and in love - again. But the past catches up with her and before England's shores are out of sight she is embroiled again with the man who ruined her life before. Doubts about Felix, and fears for her daughter left at home, sap her confidence and judgement.

The voyage from Tangier to Nice becomes fraught with danger and is indeed through troubled waters.
