I’ve a nice quick read for you. The Last Close Call by Laura Griffin is a crime thriller involving investigative genetic genealogy to find the bad guy.
This one has a romance angle so if that’s not your thing, fair warning! It also features sexual assault but not in any great detail. It doesn’t go into much detail on the DNA matching and sticks more closely to the detectives chasing the criminal down. It has a couple of side-plots but won’t tax you too much. I enjoyed it as an easy diverting read.
