The Hollow Hills Merlin the Enchanter, prophet and visionary, adviser to kings: Here is the story of how he rears Arthur, the future Christmas King, in remote secrecy, safe from the warring kings and Saxons who plot against his father, King Uther. Told in the voice of Merlin himself, this tale bristles with all the suspense and intrigue of fifth-century Britain. Ambrosius is dead, having brought order and progress to the kingdom during his reign.
...Born the bastard son of a Welsh princess, Myrdden Emrys—or as he would later be known, Merlin—leads a perilous childhood, haunted by portents and visions. But destiny has great plans for this no-man's-son, taking him from prophesying before High King Vortigern to the crowning of Uther Pendragon ... and the conception of Arthur, king for once and always.
