Searching for answers, Claire stumbles upon a pile of letters, hidden under Julia's bed in an old, battered shoebox, and feels closer to her daughter than ever before. They tell her that Julia was happy, that she was thriving at university, that she was in love. But as the letters go on, Claire starts to feel uneasy at something hidden between the lines. Even as she grieves, she must prepare to face a shocking discovery. Because Julia was hiding a terrible secret--and when it's uncovered, it might make Claire question everything she thought she knew about her daughter." -- (Source of summary not specified)
