Edgar Rice Burroughs 
Eternal Lover 

When Nu, a caveman from 100, 000 years ago, is transported via a magic spell to the present, this can only mean one thing — adventure!He falls in love with a girl who is the reincarnation of his long-lost lover, only for them to be transported back to the Stone Age. Time-travel, heroic deeds, dangerous situations, entertaining and breathtaking escapades (let’s not forget Tarzan as well) turn "The Eternal Lover" into a story about treachery, love and a fight for what is right and true. A recommended reading to fans of Burroughs, adventure fiction aficionados and readers of romantic stories.-
