With just his second book, Alex Berenson, in my opinion has joined the ranks of today's elite spy thriller writers. The Ghost War, like its predecessor featuring CIA agent John Wells, is a tension-mounting thriller that has Wells returning to Afghanistan to investigate evidence the CIA received pertaining to a surge in Taliban activity backed by an unknown foreign power. But what he finds there is far from what he expected. Without going into detail, The Ghost War will have you on the edge of your seat as it tells its tale of the world hurtling toward confrontation as a result of a power play in China, an Iran determined to go to nuclear, and a mole within the ranks of the CIA. As with The Faithful Spy, Berenson's The Ghost War is well-written, exciting and very true-to-life. Further, the author has created characters that are believable and interesting; and John Wells is a character I definitely plan to go along with when the third book in the series, called The Silent Man, is published in March. Like most books, The Ghost War has some very minor flaws but they really aren't worth taking up your time describing. Rest assured, The Ghost War is a very worthwhile read, but I recommend that you read its predecessor, The Faithful Spy, first.
