Something deadly has just awakened.

Donna and her husband, Greg, are stranded in Vienna when an asteroid flyby shuts down the airport. The city orders everyone to remain indoors, but determined to squeeze in one last day of sightseeing while following the restrictions, they leave their hotel for the Natural History Museum. They expect a quiet afternoon among fossils, minerals, and historic relics.

Instead, the meteorites crack open.

Spider-like aliens swarm the museum, biting visitors and absorbing them into a terrifying hive mind. Donna is bitten too, but her neurodivergent brain refuses to surrender. She can barely tolerate the voices already competing inside her head. She certainly isn’t making room for an alien one.

Now trapped inside the museum and hunted by the creatures and their human hosts, Donna must escape before they find another way to assimilate her.
