From the early days of Jenna’s stay in Penfach, the image of writing upon the sand is prevalent. She writes her name on the sand as a way of solidifying her presence in the area, even though it will be washed away. Then, she uses the images of names in the sand to make a living, implying that each momentary act can built the foundation for a life. However, the writing is not always a benevolent symbol, since Ian uses the same tactic to reveal his presence in Penfach to Jenna. Because of its transient nature, recipients of such a message question reality: “I see the writing: writing I’m not sure if I saw on the beach or in my head” (279). Contrast this with the sculpture that Jenna used to engage in—which was at once more solid and more breakable. This leads the reader to understand that the idea of permanence, at least in terms of identity, is an illusion. 

Jenna’s preoccupation with the broken door at her little Penfach cottage seems like an abstract manifestation of her emotional trauma at first. The audience is not aware of how acutely the door represents danger to her.
