In the year 1629, a young English lutenist named Peter Claire arrives at the Danish Court to join King Christian IV's Royal Orchestra. From the moment when he realises that the musicians have to perform in a freezing cellar underneath the Royal apartments, he understands that he's come to a place where the opposing states of Good and Evil, Light and Dark are waging a war to the death. Designated the 'King's Angels' because of his blond good looks, he finds himself falling in love with a young woman who is the companion of the King's adulterous and estranged wife, Kirsten. With his loyalties fatally divided, how can Peter Claire find the path that will realise his hopes and save his soul?
