Honor Bound (The Spare Heir #1)

His every wish, his every dream, was that some day he could be like his older brothers. A valiant warrior, a champion among men, that's what Jorem wanted to be. To be respected by others and loved by his father the King.
Faced with decisions that could affect an entire kingdom he must choose between the comforts of life in a castle and the grueling work of a blacksmith's servant. He'll do this, if not for his family, at least for the people the royal house should be serving. In the refiners forge he discovers his own metal even when faced with the anger and contempt of a people who have come to distrust those of royal blood. Alone he may be, but through his determination and the wisdom gained from an old man Jorem stands his ground.
He finds that becoming a man isn't about a title and prestige, sometimes it's just doing the right thing.
