No one but August Derleth could continue the Cthulhu Mythos cycle after the death of its creator, his friend H.P. Lovecraft. In a comprehensive fusion of Lovecraft's fearful myth-pattern, Dr. Laban Shrewsbury pursues his arcane investigations into the unspeakable secrets of the Ancient Ones to the drowned city of R'lyeh, where the ancient god Cthulhu waits dreaming.
August William Derleth (1909–1971) was an American writer and anthologist. Though best remembered as the first publisher of the writings of H. P. Lovecraft, and for his own contributions to the Cthulhu Mythos genre of horror, Derleth was a prolific writer in several genres, including regional writings, historical fiction, poetry, detective fiction,science fiction, and biography.
August Derleth, a Guggenheim Fellow in 1938, considered his most serious work to be his ambitious Sac Prairie Saga, a series of fiction, historical fiction, poetry, and non-fiction naturalist works designed to memorialize life in the Wisconsin he knew. Derleth was a pioneering naturalist and conservationist in his writing.
