According to Passage

Sara Hansen knows her kidnapper is not finished with her. After recieving a note from The Author, she knows she has to be careful, whatever she does. But The Author is closer to her then she expects. And for some mysterious reason, Caitlin, Maxwell's ex-girlfriend, keeps popping up in Sara's life.

Nothing makes sense, but it's Sara's job to figure it out. With everything happening, anyone could be The Author. Along with the passages that she keeps getting, bad things start to happen to her and everyone she holds dear.

Will she be able to stop The Author before everyone she loves is gone from her life?
