A radar expert named Terry Holt is recruited as part of a scientific expedition in the Philippines; his mission: to build specific types of underwater listening devices that are to be used as part of an unknown agenda. Frustrated that he is expected to work on his inventions without being given any answers, Holt looks for the truth on his own, and what he finds is completely unexpected!Creatures of the Abyss is a novel remnant of the works of giants such as H.G. Wells and Jules Verne, Murray Leinster managing to take sci-fi to the next level without the addition of robots, spaceships or anything else you might expect to see in a modern day science fiction book or movie.The nature of the illusive plot and the unique setting are enough to cloud this novel in complete darkness for the reader to gradually discover its many facets and mysteries. We are thrown into a world where unusual catches of fish and a mysterious disappearing vessel have attracted the attention, as well as the caution of the scientific community, bent on finding out the truth behind the strange “orejas de ellos” (things who listen) that were given as the sole explanation behind these happenings, by local fishermen.If you’re interested in sci-fi even remotely, you will be completely captivated by this brilliant novel. Although overall basic and lacking the complexity of many sci-fi works you may be accustomed with, you will find its simplicity to be all but addictive, and the unknown and unpredictable events encountered by the main protagonists will play an important role in creating one of the most intriguing and exciting plots in modern sci-fi history.Creatures of the Abyss is well worth reading by anyone who may be interested in an adventure and mystery novel as well, its less pronounced association with “standard” science fiction stereotypes giving it an added dimension of imaginative expression and sheer fun.
