The Caspak Trilogy (Hörbuch (Download))

The Caspak Trilogy includes three novels about the fictional island Caprona (also known as Caspak).
The Land That Time Forgot: Starting out as a harrowing wartime sea adventure, Burroughs's story ultimately develops into a lost world story reminiscent of such novels as Sir Arthur Conan Doyle's The Lost World (1912) and Jules Verne's The Mysterious Island (1874) and Journey to the Center of the Earth (1864). Burroughs adds his own twist by postulating a unique biological system for his lost world, in which the slow progress of evolution in the world outside is recapitulated as a matter of individual metamorphosis. This system is only hinted at in The Land That Time Forgot; presented as a mystery whose explication is gradually worked out over the course of the next two novels, it forms a thematic element serving to unite three otherwise rather loosely linked stories.
The People That Time Forgot is a direct sequel to The Land That Time Forgot and continues the lost world saga begun in the earlier story. Burroughs continues the revelation of his lost world's unique biological system, only hinted at in the previous installment, in which the slow progress of evolution in the world outside is recapitulated as a matter of individual metamorphosis. This system forms a thematic element serving to unite the three otherwise rather loosely linked Caspak stories.
