The New York Times bestselling author whose Tracers series has been called compelling,
mesmerizing, and knock-your-socks-off has a new forensic thriller sure to please fans of Tami Hoag and Karen Robards.

Police detective Andrea Finch is a rising star in her department until a split-second decision derails her career. Disgraced and disillusioned, she’s on leave from her job when she gets an urgent call from her younger brother. She’d prefer to ignore his latest plea for cash, but this time instinct tells her something is very wrong. Andrea’s search for answers takes her to a dusty Texas border town where danger lurks in plain sight and nothing is quite what it seems.

FBI agent Jon North is working undercover in west Texas, investigating an unsolved murder that may be linked to a terrorist plot. But when the evidence points to Andrea’s brother, Jon finds that persuading the stubborn cop to help will be harder than cracking his toughest case.

Andrea must find a way to do what’s right while protecting her only sibling. As the clock ticks down, Andrea and Jon race to confront a heartless killer who will stop at nothing to deliver a final, terrifying message.
