Night Terrors is the third in the critically acclaimed mystery series featuring psychologist and trauma expert Daniel Rinaldi.

In the midst of a brutally cold winter in Pittsburgh, Daniel Rinaldi is asked to treat Lyle Barnes, a retired FBI profiler whose terrifying nocturnal visions cause him to wake up screaming. Barnes, after twenty years spent inside the minds of the nation's worst serial killers, is not only falling apart psychologically but also finds himself the target of an unknown assassin, whose mounting list of victims is paralyzing the city. Hidden for his own protection by his former bureau colleagues, Barnes secretly escapes, drawing Daniel and a joint task force of the FBI and the Pittsburgh Police Department into a desperate manhunt. They must try to find the missing agent before the killer does.

Meanwhile, another case competes for Daniel's attention. The mother of a young confessed killer, now in jail in nearby West Virginia and awaiting trial, is convinced that her son is innocent and appeals to Daniel for help. Against his better judgment, he becomes involved but soon realizes that much about the case is not as it appears.

As time is running out, Daniel uncovers an unexpected web of murder and madness that not only connects the two investigations but also puts his own life at risk. Complicating matters further is his deepening relationship with the beautiful Detective Eleanor Lowrey. Will the danger closing in around him threaten to ensnare her as well?
