Critical and popular reaction were positive. Kirkus Reviews said that "...like Annemarie, the reader is protected from the full implications of events--but will be caught up in the suspense and menace of several encounters with soldiers and in Annemarie's courageous run as courier on the night of the escape."
In addition to winning numerous awards, the book has been one of the best-selling children's books of all time. According to Publishers Weekly, it was the 82nd best selling children's book of all time in the United States with sales above 2 million as of 2001.
