" Sparrows soar on high; they are light and agile. They fly through the clouds unafraid and travel where the skeleton could never go. That is strength on little wings. And they fly about inside the tower, waiting for the sun to go down so they can open the windows and escape out into the night sky.” “And what do they do when they come out?” “They rain tiny blessings down on the Jews of Prague while we all are asleep. They shine light in the darkness. "

― Kristy Cambron , A Sparrow in Terezin (Hidden Masterpiece #2)
