Everything you need to understand or teach The Hollow Hills by Mary Stewart.
From his conception on a stormy night in Tintagel to his supernatural crowning in the Wild Forest at Galava, the process of getting Arthur to the throne is fraught with danger and complication. Only a man with the power and foresight of Merlin could successfully carry out his ward's destiny. When Merlin meets Arthur - for the first time after his birth - the boy is nine years old and living in Galava with Count Ector, in complete ignorance of his noble birth. Over time Merlin teaches Arthur the skills he will need to be High King, follows him to his first battle at Luguvallium where his birth father, King Uther, dies, and finally brings him to the Chapel Perilous where he witnesses Arthur take up the sword that proves him to be the heir to Macsen and the true King.
