The Sea of Prickles

Escaping the clutches of the sorcerer in his island hideaway, Avalon and his three female companions set sail on Ghost Runner. Discovering an unchartered, uninhabited archipelago, they make the tropical paradise their home for six blissful months.

While there, they discover a derelict town on one of the coral atolls that had been sacked by slavers. In a hidden chamber beneath the ruins of an ancient temple, Avalon finds a treasure beyond value and, on the wall, a pictorial history of the island's inhabitants.

Avalon is told by a Spirit Being that he is to return the treasure to the rightful owners, who are enslaved in a land thousands of miles to the northwest. Ghost Runner is attacked by fierce pirates along the way, gets sucked into a giant whirlpool half a mile wide at its gaping mouth, survives severe storms, and finally arrive at their destination.

Their search for the whereabouts of the slaves leads them into extreme danger at every turn.
