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. On impulse, Claire writes back, hoping to preserve Analisa's innocent belief in answered prayers - even if Claire lost her own faith when her young son was killed in a hit-and-run accident three years earlier.Since that day, Claire has watched numbly as her life lost its meaning and her marriage dissolved, unwilling and unable to engage with the world around her. But Analisa's letters gradually draw Claire out of her cocoon and into the companionship of other Mulberry Park regulars - all, in their own way, in need of comfort. Aside from Analisa and her elderly nanny, Hilda, there's Sam, Analisa's attorney uncle; Trevor, a young boy in need of companionship; Walter, the chatty old man who plays solitary chess games; and Maria, a single and pregnant young mother of two struggling to keep her family home. As friendships grow, sorrows lift, and lives and hearts connect, each will discover just how far and how high one simple letter can reach...
