The Four return to Faracadar in this sequel to The Call to Shakabaz that charts their adventures through a siege of Big House City, the dungeons of the Final Fortress, Compost's garbage labyrinth, an alien-run prison camp, an attack of flying tacos, a voyage to the bottom of a dying ocean, and more. They apply their ingenuity to the task of overturning an ancient prophecy and preventing the environmental destruction of the land by mysterious alien creatures in cahoots with the malevolent enchanter Sissrath. Introducing the Prophet of the Khoum, a reformed geebaching, and a resourceful Latina friend, this year's return to Faracadar finds the Four taking action rather than accepting defeat as a foregone conclusion. While the danger of environmental destruction in Faracadar threatens to undermine hope, the heroes and heroines of Changing the Prophecy refuse to allow the doomsayers the last word.
