Fair Warning is the 2020 book from the author of all those excellent Harry Bosch stories.
But Bosch does not appear in this one.
It’s his 3rd novel featuring exclusively reporter Jack McEvoy,
Undetected by law enforcement, a vicious killer has been hunting women, using genetic data shared by the victims themselves to select and stalk his targets.
After reading this book you certainly will want to avoid getting your genetics checked by sites like 23andMe. There’s very little regulation. In the book women are tracked down by the killer by their genetics data.
His next book will feature Lincoln Lawyer Mickey Haller. Bosch will return after that.
He’s also currently working on #7 and last of the Bosch TV series.
