A young narrator recounts learning to read with the help of Señor Velandia, the owner of the village shop, so she can unlock the messages her older sister, Gina, receives from a young doctor each month. In doing so, she will change her life, as well as the lives of every child in the pueblo of Palenque Colombia. Inspired by stories told to the author by Colombian women, Letters in Charcoal celebrates the freedom to read and the joy reading can bring by adding light for a brighter future.
