Savage prehistoric thrills and swashbuckling action like you've never seen await as two of the greatest creations in literary history collide! Trapped within the lost island continent of Caprona, explorer Fausto Caproni, his sister Marina, and the masked bandit El Zorro desperately search for one another after being separated in a land dominated by creatures from the dawn of time. As they each battle for their lives against rampaging dinosaurs and spear-wielding primitive humans, the trio will also have to contend with the Spanish soldiers who stalk them, intent on murdering all three to claim Caprona for the Spanish Empire. This spectacular cross-over event seamlessly meshes Edgar Rice Burroughs' and Johnston McCulley's classic creations into a blockbuster tale filled with danger, dinosaurs, and drama in a once-in-a-lifetime, sci-fi/action event!
