Loved the worldbuilding and the plotline about the common cold, and then an absolutely FANTASTIC cliffhanger halfway through, and then my eyes glazed over for the rest. This is two stories jammed into one serial. Half stars for half a good serial

(I did like in the second half when the Monoid was like "oh there's someone hiding from us in this house, we should just SMASH ALL THEIR STUFF UNTIL THEY COME OUT." Peak writing)
