Query: The master is back!

I was asked if this book was good. No, it is spectacular. At first, AVENGER seems like a simple tale of revenge, but it is so much more.The story begins with the murder of an idealistic college kid in Bosnia in 1995, and a bereaved grandfather who decides to do "one more good thing." The Avenger is Cal Dexter, a kid who made his bones in Vietnam crawling down tunnels and wasting Viet Cong. The rest is waiting for you between the covers of this extraordinary book.Mr. Forsyth reminds us of what he did when he wrote THE DAY OF THE JACKAL. The same intensity, twists and turns keep you guessing right up to the end.This book deserves 10 or 15 stars.Run don't walk to your nearest book store get a copy right now!
