Stranger on Rhanna - Christine Marion Fraser

Rachel Jodl returns to Rhanna and the security of home to escape from her hectic life as a concert violinist and from the pressures that have strained her marriage almost to breaking point.
Here she meets Austrian Otto Klebb, a dark, striking man, also seeking refuge in Rhanna, whose charm and generous spirit quickly win him a special place in the hearts of all the islanders - especially Rachel's. Their love of music draw them to each other, but soon they come to share something much deeper.
Only Rachel knows Otto's real reasons for coming to Rhanna - he has blood ties with the McKinnon clan to which she belongs.
However, he is also the most renowned pianist in Europe.
Jon looks at Rachel's growing fondness for Otto with jealous unease and when she announces she's pregnant, he refuses to believe the child is not Otto's.
It takes a death and a revelation for Jon to return to his wife and child.
