Wednesday's Writing Prompt — Bookshelf

Imagine your character's bookshelf. Skimming through the titles, she pulls out her favorite book. What is it? Why did she connect with it so strongly? At what point in her life did she first read it?
Now connect this with the current circumstances in her life. Why is she choosing to go back to this book at this very moment? What comfort does it provide her with? Is her feeling for the book changed by her circumstances?
