Adventure in medieval England

You may have bad days, but they probably aren't as bad as those for the main character in Crispin: The Cross of Lead by Avi.  Life in 14th-century England is tough enough, but now "Asta's son" is an orphan with no other family and no money.  After learning from the local priest that his name is actually Crispin, the situation gets worse: the priest is murdered, Crispin is falsely accused of the crime, and the evil village steward (John Aycliffe) states that Crispin can be killed on sight. After fleeing, Crispin meets "Bear," a giant of a man who travels around juggling, and the two become traveling companions.  While in the town of Great Wexley, Aycliffe and his men capture Bear in an attempt to trap Crispin.  Will Crispin risk his life to save Bear?  Why is Aycliffe so determined to kill Crispin?  This is a page-turning adventure combined with a fascinating look at life in the Middle Ages.
