The Rose of York: Crown of Destiny

In the second book, Richard takes the throne as king of England, after the death of his brother and the declaration of the illegitimacy of Edward's children. Richard quickly tries to turn the country around, and starts trying to rid the country of corruption. He learns though as the book unfolds that men are always driven by greed, and as small revolts turn up about the king, mostly driven by Elizabeth Woodville, he tries harder and harder to turn the country to peace. With the disappearance of the young princes from the tower, Richard is hit with the realization that they may have been murdered, but he was blamed from the start for their deaths.
