Tegen is travelling to Mona, the sacred Isle of the Druids in the land of the Cymry. (We call it Anglesey in North Wales these days).
On the way, she is given a prophecy that she must find the Wave that will heal the Land… But when she reaches the shore, there are so many waves, how can she find the One? What does it mean?
So much seems to be against her: a pursuing demon, storms at sea, a Roman massacre, and above all, the powerful mirror magic of queen Étain of of Ériu! (Ireland)
After danger, joy, and ghastly rituals, Tegen finds what she has been hunting for – but it breaks her heart!
