Straight-A student at L’Ecole—a first-class semi-clandestine academy of Arp, Xelda da Vinci Zing, daughter of Hercule, gets assaulted by Dr. WW Wyrd, the nasty devilish bastard son of Swannie the Swan God (custodian of Lake Styx), in her own bedroom on her super-symbolic 16th birthday—a crime that launches her on a quest for a vengeful payback big-time, leading her to a robust recruitment into the WDF (Women’s Defence Force)—a secret female army run by wily Mother Clotho, who needs a sharp teen like Xelda to recruit an innocent teen-age patricidal killer whose DNA matches up with his evil rape-happy Dad—before Dad seizes the Kingship of Arp, a sad little Dwarf Planet floating in Ultra Space—and the last live vestige of what remains of Mother Earth, following Cataclysm 13.
