Avery is an obscure author whose recent disappearance is eerily similar to the death of a character in her latest thriller. Last seen walking the cliffs at Bosigran, it is suspected she fell, although her body has still not been found.

When Alex, an ambitious young journalist, receives a copy of Avery's book in the post, she becomes obsessed with finding out what happened to her.

Alex travels to Cornwall to research Avery's death for an article and discovers that the writer's life mirrored her book in more ways than one. She increasingly suspects that all is not as it seems. One question in particular keeps playing on her mind, did Avery jump was she pushed?
