"When an extinction-level virus threatens humanity, it's up to Sigma Force commander Gray Pierce to stop the catastrophe in its tracks - and the key to the cure lies in the legendary travels of Marco Polo" Absolutely! That commander is going to throw everything he has at the virus. Tanks, AA missiles, rockets, grenades. He's going to surround it and bomb it back to the stone age, and wipe it from the face of the Earth. Meanwhile the medical people will cower in terror. Any novel with a ridiculous title like this (ripping off Michael Crichton to boot) should be avoided like the plague.
