Summary
In this action-packed mystery thriller by #1 bestselling author Blake Pierce, Cora Shields, 30, former Navy Seal turned FBI Special Agent, will stop at nothing to catch a killer— but she is stunned, after bending one rule too many, to find herself fired. When a former military friend needs her to help find her missing daughter, Cora must work outside the law, hunting down diabolical killers on her own—even if it means vigilante justice.

Will Cora save the victim in time and give her life a new purpose? Or will she end up descending into a deeper hole than she ever imagined?

“A masterpiece of thriller and mystery.”
—Books and Movie Reviews, Roberto Mattos (re Once Gone)
⭐⭐⭐⭐⭐

UNDONE (A Cora Shields Suspense Thriller—Book 1) is the debut novel in a new series by #1 bestselling mystery and suspense author Blake Pierce.

On the outside, Cora Shields is a total badass. A Navy SEAL veteran and a top agent in the FBI’s Behavioral Analysis Unit, Cora has a reputation for doing whatever it takes to catch a killer. What no one knows, though, is that she’s a wreck on the inside, addicted to painkillers and deeply depressed. When Cora is fired, she is at loose ends—until she learns that an old friend’s daughter has disappeared.

Hesitant at first, Cora decides to take the case on as a vigilante—and her world soon explodes into action.

The conspiracy she uncovers goes deeper than anyone could have imagined, leading her on a wild cross-state chase to save the missing girl before time runs out.

Can Cora handle all this alone, all while keeping her own demons at bay?

Can she catch a killer, and save the girl before it’s too late?

A page-turning and harrowing crime thriller featuring a brilliant and tortured vigilante, the CORA SHIELDS series is a riveting mystery, packed with non-stop action, suspense, twists and turns, revelations, and driven by a breakneck pace that will keep you flipping pages late into the night.

Books #2 and #3 in the series—UNWANTED and UNHINGED—are also available.

I liked narrator’s voice but her accent didn’t work for certain characters, especially those in Colorado and Colombia

Profile Avatar Anonymous Apr 2023

good story line and the narrator did a good job although it would be nice to have an American accent for an American story.

Profile Avatar Dragoljub M. Jul 2025

It is what it is, repetitive but relaxing not a hard read by any means. If you have something to do while on autopilot i woiluld recomend it.

Profile Avatar Susan H. Nov 2022

Really not sure. I like this type of book and it did have some section that were quite good but …… I think the action was a little over the top and very very unbelievable.

Profile Avatar S Decelles Jun 2026

Very good.

Profile Avatar Meherunnissa M. Apr 2026

Good story whilst driving and working for me. I like Blake Pierce though I need to hear different kind of mysteries in between to enjoy him.

Profile Avatar Kathy H. Mar 2026

Good

Profile Avatar Nicole C. Jan 2026

this was a very good read! looking forward to the rest of the series

Profile Avatar Kristi W. Nov 2025

edge of my seat reading!

Profile Avatar Claudia M. Nov 2025

Not one of their best works. I agree that there wasn’t much character development. I also agree about e narrator ‘s accent… I kept thinking it was taking place in England.I really like this “author” so I’ll read the rest of the series.

Profile Avatar Anonymous Oct 2025

Could have been a great book, with an exciting story. But, it just had no substance. Zero character development. It read like an outline of a novel. Give me some nuance, some side stories, some details for God’s sake!! And the narrator? Why narrate a book about an American SEAL/FBI Agent with someone who uses foreign pronunciations of words?

Profile Avatar Lori C. Sep 2025

good story line

Profile Avatar Anonymous Sep 2025

Lots of action

Profile Avatar Jody M. Jul 2025

Was a good read with some plot twists.

Profile Avatar Latoria Jul 2025

This was a decent quick read. I love a good heroine story. I liked that though she was flawed she was still was a beast at defying the odds stacked against her! I love that the men hating on her didn't stop her drive to save lives! It's some about a women's for instinct that seems to ALWAYS be right!

Profile Avatar Samatha G. Jun 2025

Love it

Profile Avatar Anonymous May 2025

Was good narrator good

Profile Avatar Annemarie B. May 2025

Really enjoyed it. Badass character. Makes you want to listen to the whole series.

Profile Avatar Anonymous Jan 2025

Such a waste of 1 credit! the narrators all had British accents and it was supposed to be an American woman and taking place in the United States. I don't recommend this book at all.

Profile Avatar Anonymous Jan 2025

good story and narrator

Profile Avatar Anonymous Nov 2024

I really enjoyed this book. Good reading by narrator.

Profile Avatar Anonymous Oct 2024

The plot was good but if you are going to write a story about and American FBI agent and SEAL try to use a narrator that doesn’t have an accent like Diana Bustelo. Some of us deep dove into these books and sometimes can’t get over the voice.

Profile Avatar Miss Biggun Oct 2024

Really enjoyed this book to the point I was listening to it at home and not just in the car. Will be checking out what other books this author has written

Profile Avatar Anonymous Sep 2024

well done, kept my attention

Profile Avatar Marty Aug 2024

Good action book

Profile Avatar Anonymous Jul 2024

I did not really enjoy this book, not really much depth or suspense, just a lot of action. Not really my type of book.

Fabulous story. Love it. Shows how our past pushes us to keep going.

Great read

Profile Avatar Fatima E. Nov 2023

I like how it touched on the issues military personal face, especially the seals.

Profile Avatar Anonymous Nov 2023

Brilliant what’s book 2

Profile Avatar K.R.S Oct 2023

The book itself needs more detail. In my opinion there was room to give this story a real back bone, but it fell short for me. Everything was a bit too convenient, and lacked creative writing. The narrator did a good job. However, I don’t think I would have chosen a British woman to narrate a book about an American Navy Seal. She did a great job nevertheless.

Profile Avatar Anonymous Sep 2023

Did not like

Profile Avatar Penguin Fox Aug 2023

I listened to it all in one go it was that good

Profile Avatar Anonymous Jul 2023

kept my interest, fast paced

Profile Avatar Valerie B. Jun 2023

Great plot with suspense. The Narrator did a wonderful job keeping me engaged in the story.

Profile Avatar Anonymous Apr 2023

The storyline is very American with FBI, Navy Seals etc etc, so I was surprised that the narrator had an English accent. The two together just didn’t work for me.

Profile Avatar Hobnob67 Apr 2023

Really liked this book

Profile Avatar Ann M. Apr 2023

Really enjoyed this one but felt there was so much left undone

Profile Avatar Caseyja88 Mar 2023

It was pretty good. Liked most of it. But some of it was a little too much, kinda over the top with what Cora could do.

Profile Avatar Lupus.warrior@icloud.com Mar 2023

What a joy to have a kick ass save the day woman! I can’t wait to read the rest of the series

An American FBI agent with a heavy European accent

enjoyed the story and the reading.

Profile Avatar Marion S Feb 2023

Discovered Blake Pierce through the free books on Audiobooks. Enjoyed the story, but this character of Cora Shields is a bit too gung-ho.

Profile Avatar Kate M. Jan 2023

It was like a female John wick or Jack reacher so the action bits were really unbelievable, sad because the plot is so relevant

Profile Avatar Robert L. Dec 2022

Enjoyed this book liked narrator

Another great book by Blake. Well Done!
