I read this book one summer in the late 1950’s or early 1960’s? I believe my grandmother took it out of the Harwichport or Harwich Massachusetts libraries for me, as I was about 10 years old. It is set on Cape Cod and is about a Portuguese Family. The grandmother has a brooch she brought from the “old country” which is very dear to her. And her granddaughter “borrows” the brooch without permission and goes skating on the cranberry bogs, where as I assume you can guess, the brooch is lost. Grandmother turns this into a teaching moment and there is tremendous remorse, etc., etc. Magically, in the spring when the little girl is walking across the bog (or playing there or working there?), she sees the brooch encased in the ice and brings it home to her grandmother.
I do not know why this book is so memorable to me, except that I stayed on Cape Cod with my grandmother most summers and I guess it hit a chord.
I do not remember the actual title or the author (hey it was 50 years ago!), only that the book was about an inch thick and had a yellow cover with sketches of the Portuguese grandmother. I do believe the entire book was illustrated throughout , as I remember seeing a sketch of the brooch in the ice.
Anyway, not much to go on I know – any information would be much appreciated!
