Joined by the royal twins of Parros, Remus and Rinda; Suni the simian-girl and Istavan, the mercenary; Guin must cross the treacherour River Kes and journey into the badlands of Nospherous where unthinkable dangers lurk. In hot pursuit is a Mongauli army of 15,000, led by the beautiful and dangerous General Amnelis.
