Three stories: Canadian compilation of 3 Betty Neels novels. Nurse in Holland, Damsel in Green, and A Small Slice of Summer.

Nurse in Holland (Amazon in an Apron) (Harlequin Romance, No. 1385)
Who was the bride to be?

Sister Maggy MacFergus was tall, and she discovered that most men found this off-putting. When Dr. Paul Doelsma offered Maggy a nursing job in Holland, she took it. There was something special about Dr. Doelsma, and it wasn't just that he was taller than her. She was sensible enough to realize that he would never love her back - after all, Paul had said he'd already chosen himself a wonderful wife. But who was the lucky girl?

Damsel in Green
Nurse Georgina Rodman had met Professor Julius van den Berg Eyffert and his children when they were brought as casualties into her hospital, and the Professor arranged with Matron to have her "on loan" for a time to help with their convalescence. It was not long before Georgina found herself wishing she could be with them "for keeps".

A Small Slice of Summer
Letitia Marsden had decided that men were not to be trusted. Then she met Dr. Jason Mourik van Nie, and he changed her mind.

Learning to trust again wasn't easy for either of them. This time, Letitia vowed, there would be a happy ending. But then Jason got the wrong idea about one of her male friends….

Could a chance meeting set it right? Surely fate wasn't going to let a simple misapprehension stand in the way of true love?
