Four science fiction and fantasy stories by Edgar Rice Burroughs are collected in Llana of Gathol, which was first published in Amazing Stories in 1941. It is the sixth book overall and the final to be released while the author is still alive. This book is seen as an example of a writer indulging in self-parody late in their careers since the stories have a lighter tone than those in earlier books in the series.Llana of Gathol, the "damsel in distress" character performed by Dejah Thoris and Thuvia in earlier Barsoom series installments, is the focus of the stories in this collection. She is John Carter's granddaughter.Carter, Llana, and Pan Dan Chee, a young guy they pick up along the road, go on a series of adventures to safely return Llana to her home. They met an old, crazy hypnotist who has been using hypnosis to keep people alive for almost a million years. They proceed to the country of Pankor, where soldiers are stored there in frozen conditions until a battle breaks out. He finds his granddaughter, Llana of Gathol, who is being kept captive by one of those coincidences that are typical in Burroughs's works. They eventually arrive at the country of Invak, whose citizens have perfected the skill of becoming invisible. John Carter takes a plane to the remote city of Horz in quest of tranquilly.
