Mary is the heir to the throne of England, and she enjoys all the luxuries of her royal status. But when her father decides to divorce her mother and marry someone new instead, Mary is indignant. If this new wife has a son, then he will be declared the heir instead of her. This is a historical novel which is rich in historical detail, and it really makes you sympathize with the girl who was later nicknamed 'Bloody Mary'. But it didn't seem to grab my attention as much as other historical novels I've read.
