Steffy and Nelly’s sisters have to flee to Sweden, escaping the persecution of Jews in their native Austria. That means the girls will have to live here—at the edge of the world—in different families, and later in different cities, far from their parents, hundreds of miles away. No one knows how long this will last. It seems that all there is here is the sea and stones. There is no war, no persecution of Jews—but there are people who support fascism… And Steffy and Nelly themselves remain ordinary girls, even though they’re in a foreign country. Annika Thor’s tetralogy is being reissued in Russia in two volumes, with two books in each volume. The first volume includes “An Island in the Sea” and “The Pond of White Lilies.” The second volume includes “The Depth of the Sea” and “Open Sea.”
