 Crispin: the Cross of Lead
Written by AVI.
Asta's son was all the name Crispin ever had.  But, since he was only a peasant in the 1800s, the lack of name is expected. But, after the lord returned from fighting, and his mother dies, he hears the city's master and a man talking, but being noticed, the master grabs his axe and throws it, barely missing his head. After being declared a wolf's head for breaking to the Master's Mansion, he goes to the saint and asks for help. But, instead of finding the saints promises, he finds a ambush, and a dead saint. Just before leaving with his lead cross, he hears talk about him murdering the saint.
Running from his town, he runs into Bear,but not a bear, who becomes his master, and then they go to
Great Wexly. They go to on to get money, bread, and news about Crispin. When they go to the great town of Great Wexly, they go to Bear's hiding place, until Bear gets captured. Crispin swears that he will save Bear, and sneaks into the dungeon. There he meets his town's master, who Crispin "convinces" him to let him and Bear go. Until they get too the gates, they go just fine, but when there only a few feet away from it, the town master turns around, and his soldiers circle them. Bear pulls out his hidden dagger, and the two get into a fight. At the end, Bear picks up The Master, and throws him right at the swords, killing him. The book ends with Crispin getting told that he is a free man by Bear.
