Complete and unabridged, with 55 full-page plates by Evelyn Blacklock, Carl Frederik Aagaard and William Henry Davis. Tarzan searches a year for his wife in a hidden valley of Pal-ul-don, where the men have tails and the tribes worship a god who is a triceratops kept in a temple. Burroughs wrote it in 1921 and built the valley a language, a geography and a religion, then gave the ape-man a native ally who calls him Tarzan-jad-guru, Tarzan the Terrible. It is the book where his son grows up enough to fight beside him. Fifty-five plates from Sorolla, Chełmoński and others picture the wild coasts, sunset marshes and heavy industry of the years 1840 to 1921, the world Burroughs was writing from.
