I really enjoyed the first book in this series Mercenary Option, so I was excited to read this one too. I was not disappointed.
Formed by a wealthy industrialist after the terror attacks on American soil, the Intervention Force is a professional strike team called in on missions others can't -- or won't -- undertake. IFOR has already defused a seemingly impenetrable scheme for nuclear annihilation; now they are called into one of the world's hottest zones. In the Zimbabwean province of Tonga, an outbreak of hemorrhagic fever has U.S. officials on the alert for bioterrorism. Walker leads his Black Ops team into the heart of danger in the African nation to unhinge the workings of two terrorist kingpins -- the brilliant Russian Pavel Zelinkow and Al Qaeda mastermind Abu Musab al-Zarqawi -- before a cataclysm is unleashed on an unsuspecting world.
