<span>Throughout the book Lily is going through a major spiritual transformation (just like the actual author). This causes her to begin with anger and hostility and to grow into a more understanding and forgiving person. Lily runs away from her bigoted home and is forced to make this spiritual transformation, which she does.</span>
All galaxies have a dense core of stars. Spiral galaxies, however, have arms that are often visible. There are two kinds of spiral galaxies: barred, where there appears to be a line running from arm to arm through the core, and <span>ordinary, where there is no bar. @Badbunnyhunny</span>
