A psychological thriller about two teenagers teaming up with the FBI to track down juvenile serial killers. In 1982, two teenagers—serial killer survivor Emma Lewis and US Marshal candidate Travis Bell—are recruited by the FBI to interview convicted juvenile killers and provide insight and advice on cold cases. From the start, Emma and Travis develop a quick friendship, gaining information from juvenile murderers that even the FBI can't crack. But when the team is called in to give advice on an active case—a serial killer who exclusively hunts teenagers—things begin to unravel. Working against the clock, they must turn to one of the country's most notorious incarcerated murderers for help: teenage sociopath Simon Gutmunsson. Despite Travis' objections, Emma becomes the conduit between Simon and the FBI team. But while Simon seems to be giving them the information they need to save lives, he's an expert manipulator playing a very long game...and he has his sights set on Emma.

This electrifying, chilling sequel to the New York Times bestselling thriller None Shall Sleep focuses on junior FBI consultants Travis Bell and Emma Lewis with a new case that may unravel everything they’ve been working for. After a harrowingly close contact with juvenile sociopath Simon Gutmunsson, junior FBI consultants Emma Lewis and Travis Bell went their separate ways: Emma rejected her Quantico offer and Travis stayed to train within a new unit of the FBI Behavioral Science division. But the unit’s latest case is feeling eerily familiar and Kristin Gutmunsson—Simon Gutmunsson’s eccentric twin—reaches out to Travis to send a warning: Emma is in peril. When Travis and Kristin turn up evidence that points back to Daniel Huxton, the serial killer that Emma had escaped, things become more complicated. With a copycat on the loose, Emma returns to Quantico and is thrown back into her past traumas. Compelled to prevent more tragedy—even if it means putting herself in danger—Emma turns to Simon for help once again. But Simon is keeping secrets that could impact their entire investigation. Will the team be able to stop the Huxton copycat before time runs out for his next victims?

The third and final book in the None Shall Sleep Sequence. Simon Gutmunsson is on the loose... Since the disastrous events of the College Killer case, the FBI is coming to terms with the fact that while catching one sociopath, they've released another. Chillingly manipulative, frighteningly intelligent, and wholly insane, Simon Gutmunsson is the worst of the worst. Now he's free, and on the run with his twin sister Kristin, and nobody in the FBI is smart enough to keep up... Travis Bell's last investigation for FBI Behavioral Science nearly killed him. Supported by family and his partner Emma Lewis, now Travis just needs to get back on his feet. But Emma has been recruited to help the FBI hunt the ultimate sociopath, Simon Gutmunsson, and there's no way Travis is letting her go into this battle alone... Emma Lewis has gained some perspective on life, and as her emotional walls come down, she realizes that only by working as a perfect team will she and Travis have any chance of beating the Gutmunsson twins at their own terrifying game. So in a journey that will take them from Moroccan souks to Mexican Day of the Dead celebrations, the stage is set for Simon and Kristin and Emma and Travis to meet up in an epic final showdown.
