I have just started book VI, the Generals. Actually I am half way through it. The Corp is coming. I have all the books, a neighbor of kindred spirits loanded them too me. I must admit, They are a good read.
I am glad that I am not alone in reading and liking them.
I also read the Clive Cussler "Dirk Pitt" series. Inca Gold is a damn fine book.
I am about to read Atlantis Found, as soon as I am finished with The Generals.
