I don't know if this would be what you are looking for but I read a book called "The Sword, The Ring, The Parchment" by Ed Dunlop. It is the first book in The Terrestria Chronicles. It is a VERY good book and I want to get the rest in the set. It if geared toward teens. Here is what the back says.
"And then Josiah saw the King. A tall, commanding figure arrayed in an elegant scarlte robe, the King had eyes that burned like fire, and his smile radiated love and concern. Josiah gazed in wonder at the Kings's countenance. Never before had he seen such a kind face.
Josiah stole a glance at Argamor, and to his amazement, saw that the cruel blacksmith and his two henchmen were trembling. Who is this King? Josiah wondered in astonishment. I wouldn't have known that Argamor was afraid of anyone!
"I have come for the lad," the King said quietly.
Travel back in time to the kingdom of Terrestria, the realm of good King Emmanuel, where knights and their ladies live in castles and where dragons still roam (occasionally). Yet the land is at war, Evil, cruel Argamor wants the throne. And he has loyal followers placed strategically throughout the kingdom. Who will win the battle for Terrestria, and on which side will Josiah find himself"
Alive with fast-pasted action in a medieval setting, the Terrestrea allegory series encourages the reader to live as a child of the King."
You could get the whole set and the two could share it.
