Queen of the Conqueror: The Life of Matilda, Wife of William I by Tracy Borman (nonfiction)

An intense read for nonfiction, absolutely fascinating.  Five stars.  Matilda was the first crowned Queen of England, as other ladies had been only wives of kings, and the author is able to trace Matilda's movements based on charters she witnessed, mostly for land grants.  Also mentioned were several other powerful ladies of the time, and I will have fun looking them up and reading other books by Ms. Borman.
