Ethel Hofman grew up in the only Jewish family on Shetland.
This is the story of her family and childhood, and of the meeting of two diverse cultures in a unique landscape.
Fleeing Russia a century ago, Ethel's father, Harry Greenwald, found a safe haven in Lerwick, Shetland.
Liking the place, he brought over Jean after an arranged marriage.
Soon, the shop he'd set up - 'Greenvald's' - became popular with the locals as a gathering place.
Despite the hardships of living on a remote island, good food and good company were always available, and the recipes for the Jewish and island dishes prepared by Jean are woven throughout the touching, affectionate narrative.
As a unique blend of memoir and cookbook, "Mackerel at Midnight" shows how food can strengthen family and cultural bonds, and celebrates the tolerance and warmth of one Jewish family and the community that embraced them.
