"535 AD. King Cador's children inherit a land abandoned by the Romans, torn by warring tribes. Riva can cure others, but can't heal her own scars. Keyne battles to be seen as the king's son, although born a daughter. And Sinne dreams of love, longing for adventure. All three fear a life of confinement within the walls of the hold, their people's last bastion of strength against the invading Saxons. However, change comes on the day ash falls from the sky - bringing Myrdhin, meddler and magician. The siblings discover the power that lies within them and the land. But fate also brings Tristan, a warrior whose secrets will tear them apart. Riva, Keyne and Sinne become entangled in a web of treachery and heartbreak, and must fight to forge their own paths. It's a story that will shape the destiny of Britain."--Provided by publisher.
