Natalie and Dan were electric from the moment they met. Witty banter and sizzling chemistry made falling in love easy, inevitable. He was in awe of her subversive art and contagious zest for life; she was drawn to his good-guy charm and drive to succeed as a documentary filmmaker.

But that was before. Before a few little lies turned to broken trust. Before hot tempers turned to blowout arguments. Before a hundred tiny slights broke them open and exposed the ugly truth of their relationship.

And now Natalie wants Dan to know just how much he broke her.

Over the course of one fateful day, Dan reads the sixteen letters that Natalie has secretly, brilliantly, hid in places only he would find. As Dan pieces together the story she's trying to tell, he realizes that Natalie has one more message for him. And it just might send his carefully-constructed life tumbling down.
