An ancient horror deep in the Amazon jungle spins a web of nightmares to ensnare adventurers, explorers and their souls in this skin-crawling Arkham Horror novel of cosmic dread. When Arkham Advertiser reporter Andy Van Nortwick receives a mysterious reel of film in the mail, with a simple note: Maude Brion is alive and well! , he steps on a path that will lead him to the edge of madness. Brion, the famous actress and film director, disappeared a year ago on an ill-fated expedition in the Amazon rainforest, delving into the legend of the Spider Queen. Excited by the prospect of his big break, Nortwick waves the money to launch a rescue mission. He assembles a team of explorers and an enthusiastic folklorist to bring Brion back and strengthen his reputation. But deep in the Amazon jungle, the lines between fearless adventurers, dreamers and crazed fanatics blur in a web of terror.
