"Anna is a regular teenaged girl...But one day at track practice, Anna falls unconscious...but instead of falling down, she falls up, defying gravity in the disturbing first symptom of a mysterious disease. Anna's world is turned upside down...Her friends don't seem to understand, running track is out of the question, and the other kids at the disease clinic she attends once a week are a cruel reminder that things will never be the same"--Provided by publisher.
