I started the Gretchen Lowell series by Chelsea Cain and really have liked the first three so far. The first one is called Heartsick and you can check out a synopsis here: Heartsick.
There are five books in the series (not sure if there will be more), but I’ve only read three so far. So far so good for me. Worth a look-see for your friend.
Upon hearing I was finally reading Sandman, the series you’re referring to here, a friend asked, “Have you met the Corinthian yet?”
I replied, “I don’t think so.”
To which he replied, “Then you haven’t. You’ll know. And you’ll never forget.”
Truer words were never spoken.
The first one is.
Several of Michael Connelly’s books deal with serial killers, but Blood Work remains one of his best and is an excellent stand-alone read in his Harry Bosch universe. Please do not judge it by the abortion of a movie that Clint Eastwood made from it.
I guess he’s more of a psychotic killer author than a serial killer author.
