Catherine, Called Birdy , by Karen Cushman

In 1290, Catherine, a 13 year old girl, the daughter of a knight, is keeping a diary of her life at her parents’ manor house. Hilarious, moving, and surprisingly vulgar and violent, Catherine’s diary is a glimpse into life 718 years ago.

From the book:

“12th DAY OF SEPTEMBER
I am commanded to write an account of my days: I am bit by fleas and plagued by family. That is all there is to say.”
