For nearly half a century, Edgar Rice Burroughs' final work, an unfinished Tarzan novel, was locked in a vault where it became the stuff of legend. In 1995, Edgar Rice Burroughs' Tarzan: The Lost Adventure enjoyed its Dark Horse debut as a series of four pulp-magazine format books. Now, one year later, the story has been collected and reformatted into an illustrated prose novel, in the classic tradition of those prized Tarzan first editions.
