Years ago, scientists began developing the ultimate military weapon: deadly sleeper assassins housed within the bodies of teenagers. Now, Subject Seven, the dangerous alter-ego living inside a 16-year-old boy, has escaped the lab and is on a mission. His objective? To seek out others like him and build an army capable of destroying their creators.

Hunter, Cody, Gene, Tina, and Kylie: five teenagers leading typical lives, until the day they each receive a call from a mysterious stranger-and learn that their destinies are intertwined. Subject Seven holds the key that connects them all. And a vicious, bloody battle for their lives is just beginning.

From School Library Journal

Gr 9 Up-In a secret compound, several children were artificially created and genetically modified in an experiment known as the Janus Project, until the alpha of their group, Subject Seven, escaped after brutally murdering a top scientist and the guards assigned to him. Subsequently, the remaining youngsters involved in the failed experiment were wiped clean of their memories and given to adoptive parents in various locations throughout the United States. Moore's first YA novel opens years later as the five children, now teenagers, begin experiencing terrifying fugue states where it appears someone has been in control of their bodies and actions while they were unaware, sometimes for weeks at a time. It isn't until that same unknown entity calls them all together that they discover what they are truly capable of and how much the Janus Project wants to destroy them. Although the theme of this story isn't new-think Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde and the comic hero The Incredible Hulk-this updated version is uniquely appealing to teens with its underlying themes of adolescent angst, budding sexuality, and body issues underscored by violent and visceral storytelling. Moore has written several books for adults primarily in the fields of horror, fantasy, and science fiction.-Jane Henriksen Baird, Anchorage Public Library, AK (c) Copyright 2010.

From Booklist

Dr. Jekyll and Mr. Hyde meet the Incredible Hulk in this high-violence series opener featuring human genetic experiments gone wrong. Five years after his escape from an underground lab, the now-teenage Subject Seven gathers four others like himself who were supposed to have been killed but were adopted out instead. The others are unaware of their special abilities to change back and forth from ordinary teens into superstrong, superfast warriors with new personalities and few memories of their alter egos. Most of this does not become clear until well into the story, after each character wakes up covered in blood or showing other signs of having been on a rampage, struggles to figure out what’s going on, and is contacted by Seven just in time to take on squads of heavily armed troops dispatched by the mad scientist who heads the original secret project. Readers patient enough to weather each team member’s protracted introduction will be rewarded by plenty of blood-and-thunder action and the enticing prospect of more to come. Grades 6-9. --John Peters
