Margaret Haddix - Among the Enemy

From School Library Journal Grade 5–7–A continuation of the series in which third-born children must stay in hiding in order to escape certain death at the hands of the Population Police. Many characters return, including Mr. Talbot and Nina, and some of the plot elements of previous books reappear. While there is little character development, the book is fast paced, opening with a raid on the Niedler School that forces Matthias, Percy, and Alia to run for their lives. The two younger children are injured and Matthias inadvertently becomes a member of the Population Police. Issues of trust and loyalty will appeal to readers as will the twists and turns of the action. This book also contains many references to faith in God and the need to believe. The protagonist often finds solace and strength in thinking of the advice given to him by his surrogate father, Samuel, a man of great faith. This one is strictly for fans of the previous books.

From Booklist Gr. 5–8. Each title in the Shadow Children series reveals a different aspect of a dystopian future in which illegal "third children" are hunted by ruthless Population Police. In the sixth installment, Haddix zooms in on Matthias, the eldest of the three friends Nina allied with in 
(2001). While seeking help for Alia and Percy, both gravely injured during their escape from the latest Population Police raid, Matthias impulsively saves the life of an officer and must then pose as an aspiring recruit. Suddenly Matthias is hailed as a hero and whisked into the heart of police headquarters, where he finds unexpected camaraderie with his former archenemies and must contend with feelings of confusion, guilt, and grief as he uses his position to aid undercover rebels. The top-level authorities' instantaneous embrace of Matthias may bother some readers, but the brisk, efficient pacing facilitated by occasionally abrupt plot turns is precisely what has cemented Haddix's strong following among both avid and reluctant readers. Series fans and newcomers alike will devour this whole.  Copyright © American Library Association. All rights reserved
