Big John's Secret
"Big John" is a 12-year-old boy living as a serf in 13th century England, but with a mysterious past understood only by "Old Marm", who has raised him as a son and teaches him lessons and courtly behavior in secret. He is finally recognized by a knight and learns that his father was betrayed long-ago by a fellow nobleman and his nurse rescued him along with a few precious family heirlooms. After training at a castle under this knight, he sets out on the 5th Crusade (starting in the year 1218 - he is now 16 years old) as a squire - largely in hopes of finding his lost father.
