From publisher blurb:
These Monsters Are No Joke!
No one knows where the Grimaldi Strain came from. Part nanite swarm, part viral infection, part curse, part Ungol dust, the dreadful material just began appearing in reports. Reports of abandoned hospitals, burned orphanages, and blood-soaked circus tents. Report of places that had been destroyed. Torn apart. Consumed.
By Cannibal Clowns. From Outer Space.
The Grimaldi Strain turns humanoids, and sometimes other creatures, into clown-faced pseudo undead, flesh-eating horrors. They can disguise themselves as common clowns... for a time. They invade, infect, spread. And once they have turned enough of a location into more of their own kind?
They feast.
And make balloon animals. Out of entrails.
