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.

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.
