The Lost World by Michael Crichton

Something has survived. THE BESTSELLING SEQUEL TO JURASSIC PARK Six years have passed since the secret disaster at Jurassic Park. In the years since the extraordinary dream of science and imagination came to a crashing end, the island has been indefinitely closed to the public, its park dismantled, the dinosaurs themselves destroyed. Or so it was thought. But something has survived. And when a team led by maverick scientist Ian Malcolm enters the mysterious 'Site B' to investigate, they are determined that this, at last, will be the end of the dinosaurs... Michael Crichton takes the terrifying events of Jurassic Park even further in this unstoppably readable adventure sequel, told by a master storyteller.
