It’s the second decade of the twenty-first century, and terrorism has escalated almost beyond control. The Dome of the Rock in Jerusalem has been blown to bits by extremists, and, in retaliation, thousands have died in another major attack on the United States. The War on Terror has reached a deadly stalemate. Now the FBI has been dispatched to deal with a new menace. A plague targeted to ethnic groups—Jews or Muslims … or both—has the potential to wipe out entire populations. But the FBI itself is under political assault. There’s a good chance agents William Griffin, Fouad Al-Husam, and Jane Rowland will be part of the last class at Quantico. As the young agents hunt a brilliant homegrown terrorist, they join forces with veteran bio-terror expert Rebecca Rose. But the plot they uncover—and the man they chase—prove to be far more complex than anyone expects.
