A fast-paced young adult military thriller by Alan Gratz, first published in 2015. Combining cyberterrorism, espionage, and family drama, the novel delivers an action-packed story while exploring difficult questions about loyalty, patriotism, and justice.

The story follows Kamran Smith, a talented high school football player from Virginia whose older brother, Darius, is a respected U.S. Army Ranger serving in Afghanistan. Kamran idolizes his brother and dreams of following in his footsteps.

His world is turned upside down when a devastating terrorist attack strikes the Pentagon. Surveillance footage appears to show Darius helping the attackers, and the U.S. government labels him a traitor. Kamran refuses to believe the evidence, convinced that his brother has been framed or is acting for reasons no one understands.

Determined to clear Darius's name, Kamran launches his own investigation. His search leads him into a dangerous conspiracy involving cyber warfare, extremist groups, intelligence agencies, and national security. As he uncovers the truth, Kamran must decide where his loyalties truly lie—between family, country, and his own sense of honor.

Gratz keeps the pace brisk with short chapters, frequent twists, and high-stakes action, while also addressing themes of prejudice, identity, sacrifice, and the moral complexity of modern warfare.
