Catherine Called Birdy by Cushman

I just finished this book a few days ago.  It really jumps out at you.  I enjoy Karen Cushman's style and have also read her "Midwife's Apprentice".   She does not hold back when it comes to descriptions of Medieval life (sometimes it can get downright disgusting).  I believe Catherine and I have tons in common.  Spunky, stubborn with a soft side.  Not sure I would recommend it for GMB. There are a few sexual innuendoes.  Nothing explicit.  On to something a bit more academic--1776!
