When a mysterious door suddenly appears at school, the Midnight Mystery Club knows exactly what it means…
Another portal has opened.
This time, it leads to a strange museum filled with towering dinosaur skeletons, glowing exhibits, and machines that seem to be studying the past in ways no one understands.
But something isn’t right.
The displays start shifting. The fossils begin to move. And a powerful system deep inside the lab is trying to rebuild dinosaurs—not just as skeletons, but as something more.
With Orbit bounding ahead (as usual), the team must figure out how fossils are formed, how scientists piece together ancient life, and why this portal is bringing the past back piece by piece.
Because if they don’t stop it in time…
This museum won’t stay a museum for long.
