I loved book 1 in this series. Book 2, a little less, three even less, and this one least of all . With each book I saw more 'new york publisher' world views, politics, and less of the raw boots on the ground view of the world that was in the first book. In the first book it was clearly against the corruption of the DC establishment, but the second and third the neocon/globalist world view slowly crept in.
A real shame because I think this author had great potential.
