"Time will help. Time will heal."
That's what people promised. But for Laura, nothing is helping or healing. Her mother's death has left a void in her. It's made Laura realize she hardly knew her mother, and that can never be fixed. So Laura lies in her mother's bed, puts on her lipstick, reads her letters -- anything to answer Laura's questions and end her unbearable loneliness.
Then Laura finds a letter that raises more questions than it answers. Written the day before her mother's death, it's addressed to someone named Megan and speakes vaguely of "forgiveness." Laura's never heard of Megan, but Megan and Laura's mother appear to have been childhood friends who hadn't spoken in twenty-five years. What would prompt her mother to write Megan now? And what did she mean by "forgiveness"? If Laura can unveil the mystery behind the letter, maybe she'll also unveil the mystery that was -- and still is -- her mother.
But Laura's search for answers becomes an obsession. Laura can't stop, not until she knows the truth about everything -- even if it kills her.
