In a library at a quiet high school, on the third shelf from the right, two hearts begin to converse with one another without ever revealing their names. She is the 8th-grade wallflower who speaks most comfortably through letters she never dares to mail. He is the 10th-grade valedictorian who discovers one of those letters - and decides to respond. What starts as a secret transaction soon turns into a sanctuary. Through months, through years, they offer their hearts to ink, ready to dream, to hope, to fall - all without ever knowing the other person's face. Through competitions, break-ups, and hidden poems entwine their lives even more, one question lingers: When you love someone you've never met, how do you find the strength to meet them? A poignantly gorgeous story of letter-writing anonymously, growing up, and tentative, dreading, first love blooming among silences in the interstices between words.
