So Lethal

Faith Bold #22

by Blake Pierce

Deafness becomes a deadly weapon in the hands of a vengeful killer seeking liberation through silence. As panic grips those who live in a world without sound, it's up to FBI Agent Faith Bold and her sharp-eared canine Turk to tune into clues hidden in plain hearing and stop the symphony of silent slaughter.

“A masterpiece of thriller and mystery.”

SO LETHAL is Book #22 in a long-anticipated new series by #1 bestseller and USA Today bestselling author Blake Pierce, whose bestseller Once Gone (a free download) has received over 7,000 five star ratings and reviews.

FBI Special Agent Faith Bold doesn’t believe she can ever return to the force after the trauma she’s been through. Suffering from past demons, she feels unfit for duty and content to retire—until Turk walks into her life.

Turk, a former Marine Corps dog, wounded in battle, suffers from his own demons. But he never lets it show as he gives everything to Faith to get her back on her feet.

Each are slow to warm up to each other, but when they do, they are inseparable. Each is equally determined to hunt down the demons chasing them, whatever the cost, and to watch each other’s backs—even at the risk of their own life.

A page-turning and harrowing crime thriller featuring a brilliant and tortured FBI agent, the Faith Bold 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. Fans of Rachel Caine, Teresa Driscoll and Robert Dugoni are sure to fall in love.

Future books in the series are now also available.

So Lethal - a review by Rosemary Kenny.

FBI Special Agent Faith Bold and her faithful K9 Turk hunt a delusional serial-killer, in Blake Pierce's excellent psychological-thriller, So Lethal. 
Red herrings and a mounting body-count drive the non-stop action ever closer to the truth, a violent showdown...and a face-off against a nemesis from the past, in quick succession.

Grab a copy of So Lethal to see who breaks a 'sound barrier' and lives to fight on!

[Claudete Takahashi · Rating 4 out of 5]

Faith and Michael are assigned to a case where deaf people are being killed, every lead they find reach a dead end till they talk to a doctor, an otorhinolaryngologist, who may give them a possible culprit. Things escalate fast as they pursue that lead and end up identifying the killer and his motives, the bad part is that he's able to take Turk and Faith out of action with some special sound paraphernalia but in a joint effort with local police he is finally secured and put behind bars. Faith will also become face to face with the Messenger Killer which will almost cost hers and Turk's lives. Easy to read and highly entertaining!
I thank Ms.Pierce for this ARC.
