The Young Elizabeth by Alison Plowden (nonfiction)

This is the first book of Plowden's "Elizabeth Quartet" and it covers her childhood through coronation. I thought it was a zippy and comprehensive read, although there aren't too many details known about Elizabeth's very early life.  Plowden put the facts together in a pleasing and interesting manner, and her points about assumptions made by many historians rang true with me.  For instance, many have assumed that requests for money for clothing and supplies in the years after Anne Boleyn's death meant that Henry was deliberately slighting Elizabeth, refusing to take care of  her.  Plowden interprets the situation as an oversight, in which Henry simply didn't realize the girl was growing out of her clothes so fast.
