Indiana Jones Series by Rob MacGregor, Martin Caidin and Max McCoy

Series of novels about Indiana Jones' adventures leading up to the movies.
In 1981 a new hero like no other burst upon the scene. Over the next ten years and three films we grew to know and love the legend that is Indiana Jones: bold adventurer, swashbuckling explorer, he lives forever in our imaginations, unraveling the mysteries of the past in a time when the world was at war and dreams could still come true. Now, in an all-new series of novels officially licensed from Lucasfilm, we will learn what shaped Indiana Jones into the hero he is today.
