A short but intense story about a strange phenomenon that forces a group of strangers together in a campus library. When the slimy rain starts, nobody knows what's going on, but soon the confusion turns into accusations and aggression when someone remarks that the rain may carry some dangerous contagious kind of virus. Those who got in contact with the strange substance are 'quarantined' in a section of the store and soon voices get loud that they must even leave the building. As the situation escalates, it reveals some nasty aspects of human nature, and I absolutely loved the unusual ending. However, while the plot was what kept me glued to the pages, I didn't care much for the characters and even less for the relationship dramas which occupied too much space.
