Ruta Sepetys said this quote

In 1991, after fifty years of brutal occupation, the three Baltic countries regained their independence, peacefully and with dignity. They chose hope over hate and showed the world that even through the darkest night, there is light. These three tiny nations have taught us that love is the most powerful army. Whether love of a friend, love of country, love of God, or even love of enemy- love reveals to us the truly miraculous nature of the human spirit.
