First, just one very small quibble. Why call the Woodville family "England's most infamous family" (as in the title)? This suggests they were wicked and criminal, which is utterly misleading.
Fortunately the actual book is much more accurate and descibes carefully and grippingly the rise of the family, with the young widow Elizabeth Woodville (nee Grey) becoming the wife and Queen of Edward IV and mother of his children. Tragedy ensued after Edward's death, with the two young sons being usurped, imprisoned and reportedly murdered by Edward's brother Richard III. Richard had other members of the Woodville/Grey family judicially murdered, including a son of Elizabeth by her first marriage and one of her brothers.
In the male line, the Woodville family died out, but Elizabeth posthumously has had the last laugh. Her eldest daughter, also Elizabeth, married Henry VII (Tudor) and was not only the grandmother of the famous Queen Elizabeth I, but is also the ancestor of the present Queen Elizabeth II, who thus carries a few drops of Woodville blood.
