Will is a small, clever orphan who dreams of becoming a knight but is rejected from Battleschool due to his size. He is instead apprenticed to the mysterious Ranger Halt, learning stealth, archery, and tracking. When the kingdom is threatened by the malevolent beast Kalkara and the exiled warlord Morgarath, Will must use his new skills to help Halt on a dangerous mission that will test his courage and prove that heroes come in all sizes.
