The Twenty Three by Linwood Barclay
Read all 3 back to back! I would recommend you read the other 2 books first as the trilogy spans over a very short time (only a few days) and even though the author re caps you will get a much better understanding of both plot and character if you read the whole trilogy.
It’s basically about a town called promise falls, the lives of some of it’s inhabitants and how their lives intertwine with the major events that happen over a couple of weeks.
A good plot and enjoyable believable characters. As always another good read from Linwood Barclay
