The Witches of Estcarp defeated Pagin of Karsten when they caused The Turning, a massive cataclysym that moved mountains to block the invasion. But the witches' enormous use of magic crippled their powers and brought chaos and destruction to all of Witch World.

Each volume of the "Turning" trilogy consists of two parts. Storms of Victory comprises "Port of Dead Ships" and "Seakeep", both co-authored by Andre Norton and P.M. Griffin. Various editions feature cover art by Dennis A. Nolan, with interior maps by John M. Ford. This book was apparently first published as Volume 4 of Tales of the Witch World.
