Years after being rescued from Isla Sorna, Billy Brennan can’t shake the nightmares of the island—pteranodons, the Spinosaurus, and most of all, the decision to take the Velociraptor eggs. His reputation in the paleontology community is tarnished, and Alan Grant still holds him at arm’s length despite their shared survival.

When a mysterious benefactor offers him a chance to return to Isla Sorna to document the island’s changes before it’s permanently closed to the public, Billy is torn between redemption and fear. The expedition promises valuable research, but whispers circulate that InGen has been hiding something—something worse than the dinosaurs.

As Billy steps back onto the island, he must confront not only the dangers lurking in the jungle but also the ghosts of his past. Was his survival truly a second chance, or has the island called him back to finish what it started?
