Prince of Scorpio is a science fiction novel by British author Kenneth Bulmer, written under the pseudonym of Alan Burt Akers.

Instead, Dray Prescot finds himself on an unknown beach on Kregen, after having spent some time on Earth without mentioning how long and where.

Prescot has once more been returned to Kregen by either the Savanti or the Star Lords, this time to save a group of prisoners from a stranded ship who are being killed by their guards.

Prescot is made welcome in a simple village full of old people but falls ill from drinking the poisonous canal water of Vallia.

While slowly recovering, he has a first-hand experience of the mercenaries taking food from the village, with Prescot unable to interfere because of his illness.

He travels south by canal boat and eventually reaches the capital of Vallia, Vondium, to find that Delia and the Emperor have both gone west to the Blue Mountains.

On his journey there, Prescot joins a caravan which incidentally carries the dowry for Delia's wedding to a local lord, arranged by her father.

On the way to the executioner, Prescot is rescued by Seg, whom he believed to be dead and who is now a member of the Imperial Guard of bowmen of Loh.

Dray Prescot makes a full recovery and returns to the imperial palace, now as the Strom of Valka, positively impressing the emperor.

Prescot is approached by a representative of the Ractor party who wishes to gain his support for their candidate to wed Delia, Vomanus.

Warned by Vomanus, the emperor and Delia have escaped to a place called the Dragon's Bones, and Prescot follows them while sending Inch to the Blue Mountains to organise help.

When the leader of the uprising, Kov Naghan Furtway, arrives, Prescot's true identity is discovered and he escapes to the emperor's party.

Prescot also learns that the Vomanus is Delia's half brother, a son of her mother from a previous marriage, but is told that this is to be kept secret.
