Seventeen-year-old Amanda Obermann (code name: Iris) has more on her mind than usual. As a member of a covert government organization called the Annum Guard, which travels through time to keep history on track, Iris has been getting some particularly stressful assignments. Plus, Jane Bonner, the Guard s iron-fisted new leader, seems determined to make life as hard as possible. Thankfully, Iris has Abe (code name: Blue), her boyfriend and fellow Guardian, who listens to her vent and helps her cope with her mentally ill mother s increasingly erratic behavior.
When Guardians start to disappear on their assignments, Iris makes a terrifying discovery: a blackout squad is targeting anyone who gets in the way of a corrupt force that s selling out both the Annum Guard s missions and Guardian lives. Together, Iris and Blue must go undercover to untangle the Guard s elaborate web of secrets and lies. But when Iris discovers that the terrible truth may involve her own father, a former Guardian undone by his own greed, she must decide how much she s willing to risk to rescue her friends and how dangerous the consequences will be for all of humanity.
A thrilling time-traveling adventure that spans from Abraham Lincoln s assassination to the Cuban Missile Crisis and back to the present day, this pulse-pounding sequel to "The Eighth Guardian" reveals that playing with time can turn into a deadly game."
