Astronauts vs. Dinosaurs! 150 years in the future, NASA Mission Specialist Kim Chang identifies a 400-million-year-old alien artifact. Earth has been visited by aliens throughout its history, and there's a wormhole at the edge of our system that could take us to their doorstep. The International Space Agency ship Michael Collins is sent on a mission to find out who visited our world, why, and what happened to them. They discover an impossible planet, Earth-like but larger than Jupiter. It seems to defy the laws of physics. When a crew lands on the planet, they find a patchwork of self-contained environments, each larger than a continent. The three astronauts investigate a compound made of up pyramids . . . filled with the skeletons with DNA identical to actual Egyptians. Now, the astronauts have a new mystery to solve. What killed these people? And is the danger still out there? Stepping outside after narrowly escaping deadly traps, they discover a living, breathing dinosaur, and the team theorizes that this place may be Eden, the source of all life on Earth. The truth, however, is much, much stranger. And far more dangerous.
