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.

    By llbmb
    I loved the suspense thriller book. Lots of twist & turns with the characters. Highly recommend it.
  • Great New Series

    By Angeltobe
    The Cora Shields Navy Seals/FBI series is a fast pasted blow you out of the water thriller. This chick can barely color outside the lines anymore and her life is screwed but when a case fall in her hands she can’t walk away. She’s not one for following rules, she makes them up as she goes along. What a page turner this one turned out to be. I was given an arc in return for reviewing this book in my own opinion.
  • Pure adrenaline

    By Lesli_Silva
    Cora Shields left a career as a Navy SEAL and joined the FBI. One of their most proficient agents, PTSD held onto her tightly and created habits for dealing with it that were not allowed. On her own, she attends the funeral of a fellow SEAL and discovers a troubling pattern of missing girls that leads her into a personal mission with some old friends. I loved this book. The adrenaline and action kept me turning pages until I reluctantly finished in one sitting. Cannot wait for book two.
