• When Charlie Summerfield unexpectedly commits suicide, his friends are left devastated and a complete shell of the people they used to be. Nobody is okay, but nobody cares. With nothing left to lose, Charlie's best friend, Harper, decides to start writing letters to his deceased companion. Obviously, Harper is past the point of being heartbroken about what happened- he's past the point of caring. So far past, that he's resorted to drinking to solve his problems. But when someone starts responding to the letters, signing them 'C.S.', the world becomes a much bigger place than Harper could've ever possibly imagined as he chases the letter writer- and his dwindling last hope- around the world for answers. He finds himself in a constant battle of faith on his journey to discovering Charlie.
