The book begins by introducing members of the COE (Celebrants of Earth), a group that randomly blows up small oil refineries to disrupt oil shipments from the Middle East. While not benign, the COE had a conscience and avoided injuring anyone or taking lives. The genius of the group, Matthew Spenser, has a fanatical hatred towards terrorists because his parents were killed by a bomb in London. He is front and center throughout the book because he built a really serious, BIG PAYOFF, bomb that is the size of a fifty-cent piece. Imagine a bomb that can get lost in your pocket change or that could be dropped in any niche or corner and be completely overlooked, and the computerized trigger can be thousands of miles away from the bomb? The new bomb got the attention of the big honchos in the Middle East so “the most dangerous assassin in the world” is sent off with a few million dollars and a hidden agenda to recruit Matthew. The assassin, Zahir Damari, cozies up to Matthew with a false agenda of killing terrorists. And so the soup (er...plot) thickens.During an investigation of a tip, FBI Special Agents Michaela Caine and Nicholas Drummond were five minutes away from the explosion of an oil refinery in NJ. As early responders, they helped rescue people and became immediately entrenched in apprehending the COE. This bomb killed 15 people. You will not want to put this book down, everything moves fast, the dialogue is crazy good and the story is divided into mere days that are easy to follow notwithstanding that it covers moving events around the glove, from NY to the Middle East, London, D.C. and Virginia.The characters are complex and incredible: old favorites (Dillon Savich and his wife Sherlock) show up, as well as the some of the FBI top shelf we are familiar with and new characters that include the President, attending Middle East peace talks in Geneva and the Vice President who is simultaneously being briefed that nuclear facilities in Iran have gone live (facilities they won’t let UN inspectors close to), plus we meet the Directors of the National Intelligence Agency and the CIA and various spook and secret service operatives and protectors.My love affair with Coulter books goes back more than three decades. Coulter teamed up with J. T. Ellison and THE END GAME is their third book. This book is the epitome of what Oscar Wilde said, "Life imitates art far more than art imitates Life." I know this book was being written before the current events in America but it is chilling how realistic this is compared to current events we currently live with - this is a timely and a GREAT book.
