Angus MacBain is unaware that his ancestral roots hail from an ancient sect of Scottish kings. When his dying grandfather gives him a dragon pendant, thirteen-year-old Angus learns of a legacy that will take him across an ocean to the island of Iona and thrust him into a heritage he did not know he had. He soon discovers that his mother, whom he had believed dead, is really a seal fairy, in hiding from a dangerous enemy. To save her, Angus must undergo a perilous journey of destiny and power to battle an evil Dacian knight and those who serve him. With only his family shield and the advice of a wizened vampire hunter to protect him, Angus must navigate dangerous terrain and dark enemies, in a land where the past and the present mingle, and sleeping kings wake.
