Each day after work, Claire Harper drives to Mulberry Park and jogs for miles, hoping to find a respite from her sadness. It's a futile effort, until the evening a letter falls from its hiding place in a nearby tree. Inside the bright pink envelope emblazoned with the words "To God From Analisa" is a note written by a seven-year-old girl, urging God to look after her parents in Heaven and help those she loves on Earth.
