"While Grace waits to see her doctor, she finds an old book that transports her to 'once upon a time...' In the old kingdom, four dragons are making people sick. One young warrior sets out to gather each of the dragons' stones, which hold the key to protection. The warrior will need her skill, bravery, and her knowledge of the dragons -- along with some help from a friend -- to succeed on her adventure. How is getting a vaccination a little like conquering dragons? Find out as Grace discovers life beyond vaccines."--From back cover.
