She left the NYPD in the firestorm of a high-profile case gone horribly wrong。 Three years later， the ghosts of her past roar back to terrifying life。

When NYPD undercover cop Laney Bird's cover is blown in a racketeering case against the Russian mob， she flees the city with her troubled son， Alfie。 Now， three years later， she's found the perfect haven in Sylvan， a charming town in upstate New York。 But then the unthinkable happens: her boy vanishes。

Local law enforcement dismisses the thirteen-year-old as a runaway， but Laney knows better。 Alfie would never abandon his special routines and the sanctuary of their home。 Could he have been kidnapped—or worse？ As a February snowstorm rips through the region， Laney is forced to launch her own investigation， using every trick she learned in her years undercover。

As she digs deeper into the disappearance， Laney learns that Alfie and a friend had been meeting with an older man who himself vanished， but not before leaving a corpse in his garage。 With dawning horror， Laney discovers that the man was a confidential informant from a high-profile case she had handled in the past。 Although he had never known her real identity， he knows it now。 Which means several other enemies do， too。 Time is running out， and as Laney's search for her son grows more desperate， everything depends on how good a detective she really is—badge or no。
