John Clark is the ex-Nacy SEAL from the book "Without Remorse". He continues his secret operational missions by creating the a group the governments of the world keep "in the black". Few people know of its existence. John is head of RAINBOW SIX. They are better than the best!They combat terrorism mostly. They are called in when no one else can handle the job. To save the lives of hostages, they "take down" the terrorists. Forget prisoners! When Rainbow Six goes in it is eliminate! The hostages are their only concern. Of course, terrorism is not the only thing Rainbow Six combats, but it is the biggest.***Tom Clancy brings it all to life! Not only are you riveted to your seat by the action and efficiency of the team (which is made up of several nationalities) but by the plot which slowly comes to a boil between it all. I highly recommend this one!***
