Yes - A new book from Meg Gardiner. Shadowheart is an addition to the Unsub story.

"FBI Profiler Caitlin Hendrix is working a case with a copycat serial killer whose crimes have a connection to another killer - Effrem Goode. Caitlin must unravel the connection between the two if she has any hope in stopping the copycat."

I really like this story from Gardiner. There are lots of connections that Gardiner shows us a little at a time. But the final reveals have lots of a-ha moments. She does a great job tying things together.
There are multiple psychopaths in this story and all are terrifying.
There is a side story continued from the previous books about a character called The Ghost that is not resolved but has some interesting continuation.
There are several names to keep up with - that was my only struggle. By the time you get to the end though you'll know them all.

Hillary Huber does a great job with the audio, especially with the wild, explosive ending.

Great story from Gardiner.

I absolutely loved this! The premise was so intriguing! Twisty! Dark! I could not get enough!

This is my first time hearing only this author and after searching 3 books store in Western Australia, 4 libraries, audible and the kindle store I'm so annoyed to see how underrated Meg Gardiner is! Why can't I find her ANYWHERE!!

PLEASE FOR THE LOVE OF GOD PUT THE UNSUB BOOKS IN AUDIBLE OR KINDLE IMMEDIATELY!..... LIKE NOW!
.......... no but seriously do it!
