This is a gorgeous (mostly) wordless children's book that beautifully captures the importance of letters for political prisoners. Having worked in a correctional facility, I can say with confidence that the letters inmates of any kind receive are one of their most important tethers to the world outside -- and this book beautifully renders that concept. The author also includes information about how to get involved with Amnesty International's letter writing campaigns at the back, should a reader be so inspired.
