She's lost her faith that they exist.
But could they find one together?

January is a hopeless romantic who likes narrating her life as if she's the heroine in a blockbuster movie.
Augustus is a serious literary type who thinks true love is a fairy-tale.

The catch? They have to swap genres.
The risk? In telling each other's stories, their worlds might be changed entirely...
