This is a small masterpiece, just 146 pages long. It is set near Katowice, just inside German-occupied Poland, in 1940 and 1941. The central figure is fifteen-year old Gracian Sofka. By day he works in the darkness of a German-run coal mine; but what gives meaning to his life is the sight of the starry heavens at night. His enchantment is enhanced when he is given a telescope, through which he discovers new dimensions and meanings not only in the heavens but on earth when he turns the instrument upon it. The meanings, however, though initially inspiring, will turn out to be far from comforting.
There is a close and touching relationship between Gracian and his largely taciturn and somewhat enigmatic brother Pawel, twelve years his senior. There are some mysteries about Pawel's past life, which will be revealed in due course; but they have little bearing on the tragic climax of the book at the end. A tragic end is hinted at early in the book. When it comes, it is not what the reader expects, but it is as perfectly crafted as is the rest of the book.
The language is simple, but poetic; and the descriptions and images are memorable.
