Cross, Janine. Touched by Venom: Book One of the Dragon Temple Saga. Roc, 2005.
Second, as our protagonist moves from situation to situation and place to place, things rarely seem to improve all that much, and that's rough. Cross does a great job of paining the desperate picture of someone who has no home, no real positive long-term bonds. (I'm simplifying a bit, but the bonds she does have are complicated, and definitely not anything you could call positive without serious qualifications.)
