About this listen
In this action-packed mystery thriller by best-selling author Blake Pierce, Cora Shields, 30, former Navy Seal turned FBI Special Agent, is fired from the FBI for breaking one rule too many. But when a former friend-turned-prostitute comes to Cora for help, swearing that neglected prostitutes are being abducted by serial killers, Cora cannot turn a blind eye—and finds herself in the race of her life to save a woman from a killer’s hands before it’s too late.
Unstable is the sixth novel in a new series by USA Today best-selling author Blake Pierce, whose best-seller Once Gone (a free download) has received over 7,000 five star ratings and reviews.
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.
Sometimes, cases need to be pursued outside the law.
With no backup, Cora is finally free to act, to bend as many rules as she needs to, at any cost, to bring killers down.
She has found her new calling. But will it also be her undoing?
A 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 listening late into the night.
