Elizabeth Rockwell writes three letters as she nears her death bed. One is written to her dear Brad, a man who adored her from the moment they met. A moment that happened after Elizabeth has given her daughter up for adoption. A daughter she never told him about. Her second letter is addressed to Maggie Shaw. A woman, a rising Hollywood actress, who never considered that Elizabeth was any more than an aunt, despite their nearly mirrored complexion and attributes. The final letter is written to an angry teenage boy in a small town in Mississippi. Norman Scott battles daily on whether to be bitter at his drunkard father, the mother that abandoned him, or at God, for taking his little sister in an accident that ruined his once happy family. Three letters sent out and read. Worlds are shaken. Families are divided. Lives are broken into two: before and after the mailbox flag was raised. But can those same letters, this same dying wish of a beloved woman, bring healing to two broken souls, love to a teenager desperate for hope, and restoration to a separated relationship?
