Uncertain Summer — Betty Neels

Serena had given up her job and gone to Holland in order -- as she thought -- to marry Laurens van Amstel who had proposed to her after a whirl-wind romance.

So it was mortifying, to say the least, that soon after she arrived she began to realize that Laurens was trying to back out of the situation -- that, in fact, he had every intention of marrying another girl.

His cousin Gijs had an answer to her problem -- but wasn't it rather a drastic one?

Hero: Gijs van Amstel
Heroine: Serena Potts
