Sisters Steffi and Nelly have to flee to Sweden to escape persecution of Jews in their native Austria. This means that the girls will have to live here, on the ends of the earth, in different families, and then in cities. Hundreds of miles from my parents. It is unknown how long this will last. It seems that there is only sea and rocks here. There is no war here, there is no persecution of Jews, but there are people who support fascism... And Steffi and Nelly themselves remain ordinary girls, albeit in a foreign country. Annika Thor's tetralogy is republished in Russia in two volumes, two books in each volume. The first volume includes the books “Island in the Sea” and “White Lily Pond.” Source:
