Stanislaw Lem's Highcastle is at once a remembrance and a meditation. Even as Lem gives an account of his childhood in Lvov in the years between the two world wars, he ponders the nature of memory, innocence, and the imagination.

His recollections of growing up the son of a bourgeois doctor at Number 4 Brajerska Street are stunningly evocative, re-creating with acuity a boy's perception of the world around him: his gossipy French tutor; the magical window of Zalewski's Confectionery; his father's anatomy books and carefully hidden French pornography; a trip to Klaften's Toy Shop; an aborted visit to a tattooed lady at the Eastern Fair; the trams, organ grinders, and halvah stands of Lvov.
