Tarzan of the Apes by Edgar Rice Burroughs
I saw this book in the “New Science Fiction” section at a local bookseller. So “new” means published in the last 100 years, since this book was originally released in 1912! It is a classic, well worth the reprinting. One of the favorite early childhood books of both my brother and myself. I still have that hardcover edition with the Ape-English dictionary in the back.
