You cannot change the beginning, but you can change the ending. After the death of her brother, Luise makes a radical change: she parts ways with her mouse-gray self and her hair. All that remains is three millimeters and a wall that no one can see behind. When Jacob and she meet, he is immediately fascinated by her. But Luise keeps her distance. Until, on her sixteenth birthday, she unexpectedly receives an email from her deceased brother - the first of many. With these messages from the afterlife and the reserved Jacob by her side, Luise manages to discover the sparkle of her life amidst this tumultuous and sorrowful time.
