FBI Special Agent Faith Bold and her K9 German Shepherd, Turk, have gained a reputation for solving even the most perplexing cases, but when victims of a new serial killer are found left in plain sight, in the busiest train stations, Faith—and Turk—are stumped. The overwhelming amount of sensory information and the muddled crime scene make the killer untraceable. This time, Faith will have to help Turk, as the two of them watch each other’s backs as they walk into a deadly trap that seems set just for them. 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.
