"The first is a man who needs you and will use you. He will weaken you dangerously. The second is a man you betrayed, though you believe otherwise. He wishes to kill you and can do so easily. The third is a ship that is more than a ship. She grieves and broods. She will carry you to your grave."

These three warnings greet Merlin on his return to the deserted fortress of Taurovinda - the Hill of the White Bull in Alba, the future England. He is not the only one making the journey: Urtha, High King of the Cornovidi, is coming home to reclaim his stronghold, and Jason is sailing in on the Argo to seek his younger son, hiding somewhere in the kingdom.

But Urtha's fortress has been taken by warriors from Ghostland; they claim it as their own. There will be war against the Otherworld.
