Strangers: Dean Koontz

This was a fast paced climax building book, but you pretty much know from the start it will be about Aliens... The book introduces you to several characters and at first you don't know how they are going to come together, but then they start getting the same obsessions. Night and the moon. Some of the characters commit suicide or seemingly go crazy before we learn they were all at the wrong place at the wrong time and were brainwashed. The remaining people who are lapsing from the brain wash go back to the hotel the incident happened. The military starts following them around.
