A teenager nearing the end of high school, Skye is protective, fierce, and yet vulnerable in important ways. The most important concept of the book, the idea of being able to save somebody, is of utmost importance to Skye herself, who tries to save and protect those around her, especially Anna and Jessica, even when their problems are so deep that they go beyond what Skye could possibly do for them. Skye even fantasizes about saving Virginia Woolf, showing the utter impossibility of her dreams. In the end, the only person who Skye can really save is herself. Once she starts doing this, with Lorri's help, she gets the strength to support her mother, despite their rocky past.
The idea of home is also particularly important to Skye. This may stem from the fact that she and her mother had to leave Los Angeles together, but also shows vulnerability on Skye's part. Skye adores their house in Santa Barbara, for example, and has done a lot of work on it herself. She loves to walk around and look at neighborhood houses; and she even sneaks into a stranger's house in Los Angeles. Ironically, at the end of the book, she is more comfortable with herself without a home than she ever was with one.
