Philip Jose Farmer wrote some of the best patiches in adventure fiction. Farmer wrote convincing adventures of Doc Caliban (Doc Savage), Lord Grandrith (Tarzan), and Sherlock Holmes (The Adventure of the Peerless Peer). Gods of Opar collects three novels: Hadon of Ancient Opar, Flight to Opar, and The Song of Kwasin. Hadon of Ancient Opar was first published in paperback by DAW Books in 1974. Hadon of Ancient Opar and its sequel, Flight to Opar (1976), explore the ancient prehistory of the lost city of Opar, created by Edgar Rice Burroughs for his Tarzan series. Farmer’s Opar books have been out-of-print so this new Subterranean edition is welcome. In addition, the unpublished third novel in the trilogy, The Song of Kwasin is included in this wonderful volume. This is a must-buy for Philip Jose Farmer fans!
