Throughout the novel, Julian carries the notebook with him, studying it, pondering the purpose of the lists, but he can't ever figure it out. In the same way that Julian doesn't understand the meaning of his mother's lists, Julian moves through his life perplexed at why his parents had to leave him. After he almost dies in the trunk from Russell's abuse, Julian is convinced he must go get his mother's notebook. The notebook is so important to him that Julian risks his safety and the safety of his friends to go back to Russell's house and search for it. As Julian finds other coping mechanisms for life, and after the threat of Russell is no more, Julian rips up the notebook.
