On Order



Seventeen-year-old Cassie Hobbes has a gift for profiling people. Her talent has landed her a spot in an elite FBI program for teens with innate crime-solving abilities, and into some harrowing situations. After barely escaping a confrontation with an unbalanced killer obsessed with her mother's murder, Cassie hopes she and the rest of the team can stick to solving cold cases from a distance.

But when victims of a brutal new serial killer start turning up, the Naturals are pulled into an active case that strikes too close to home: the killer is a perfect copycat of Dean's incarcerated father-a man he'd do anything to forget. Forced deeper into a murderer's psyche than ever before, will the Naturals be able to outsmart the enigmatic killer's brutal mind games before this copycat twists them into his web for good?

With her trademark wit, brilliant plotting, and twists that no one will see coming, Jennifer Lynn Barnes will keep readers on the edge of their seats (and looking over their shoulders) as they race through the pages of this thrilling novel.

Booklist Review

Barnes follows up the promising debut title The Naturals (2013) with a fast-paced, stand-alone sequel. Cassie, Dean, Lia, Sloane, and Michael are 17-year-old FBI protégés in a secret program that trains gifted teens to solve criminal cases. Supposedly, they only work on cold cases, but when a grisly murder occurs on a nearby college campus, they immediately start working on the case, despite the FBI's orders. What complicates matters is that the murderer is using the same methods as imprisoned serial killer Daniel Redding Dean's father. Narrator Cassie gradually uncovers more truths about her fellow Naturals, and a fuller picture emerges of the group of gifted, misfit teens. Perhaps most intriguing are the chapters written in the voice of the killer(s), titled You in a nod to Cassie's method of profiling killers. Although the action follows standard plot devices (first real suspect is next person found dead), Barnes knows how to keep the reader hooked, and fans will be eagerly reaching for this title and hungry for the next in the series.--Carton, Debbie Copyright 2014 Booklist

School Library Journal Review

Gr 9 Up-Cassie and her teenage partners in an FBI secret-criminal-investigation division are recovering from trauma and injuries resulting from the high-profile serial murder case they solved in the first book, The Naturals (Hyperion, 2013). Not only did they lose their leader turned serial killer, Agent Locke, their involvement provoked the attention of FBI authorities and they are now faced with the stoic, by-the-books replacement, Agent Sterling. Suddenly the Naturals are struggling with curfews and study sessions and are confined once again to cold cases. However, they are quickly involved in an ongoing investigation connected to Dean, the pensive and restrained profiler whose father is currently serving prison time for murder. In the course of the investigation, the Naturals are able to use their skills to find answers to aide the FBI. These answers come at a price; Dean must face his father, Cassie winds up confined to the house, and the other team members take considerable risks to acquire interviews and information. Readers will want to be familiar with the first book since the characters' skills and previous relationships are assumed information. The engaging plot moves at an even pace, though a bit slower than its predecessor, and the murder mystery is compelling. The love triangle among Cassie, Michael, and Dean continues and development of all the characters is furthered with revelations of their past. This is a definite purchase for libraries that were served well by the first title.-Lynn Rashid, Marriotts Ridge High School, Marriottsville, MD (c) Copyright 2014.
