What is the author's style in The Princes in the Tower by Alison Weir?

Alison Weir is the author of The Princes in the Tower. Weir is a well-known popular British historian who frequently writes about the English Royalty in the 15th and 16th centuries. She has written extensively about Henry VIII, Elizabeth I, and the Wars of the Roses. The Princes in the Tower is simply one more work within a large body of work concerning the time period. Weir writes The Princes in the Tower with the intention of vindicating the claim that Richard III had the Princes in the Tower killed. Thus her bias is clear: she has it in for Richard III.
