Land of Terror is a 1944 fantasy novel by American writer Edgar Rice Burroughs, the sixth in his series about the fictional "hollow earth" land of Pellucidar. It is the penultimate novel in the series and the last to be published during Burrough's lifetime. Unlike most of the other books in the Pellucidar series, this novel was never serially published in any magazine because it was rejected by all of Burroughs's usual publishers. Source: Wikipedia (en)
