Thus far, every Joe Ledger book has been consistently good, and this is one of the better ones. The formula is simple - Joe and the DMS (Department of Military Sciences) take on various classical monsters and madmen, re-imagined in more realistic scientific versions. In this one, the crew has to deal with a band of "vampires" (Really an evolutionary offshoot of humans with greater strength and speed and blood drinking, who have garnished their own rep over the centuries as beasties of legend) who obtain nuclear devices from an ongoing series Big Bad, Hugo Vox of the Seven Kings, who functions as their Blofeld. 
 And the books are fun as hell - Take the crazy plots of 60's James Bond films and drop them into the techno-tension style of Tom Clancy and stir in some monsters and there you have it. Vampires with nukes are a threat to the entire world and so Joe and Echo Team jump into action to unravel centuries-old mysteries and put bullets between a lot of fangs. Each book reads like a more snarky, cynical, and modern rendition of a Doc Savage story. Heck, just enjoy the character names... Mr. Church, Warbride, Hugo Vox, Violin, Ghost, Nicodemus, Bunny, Top, and more. They may not be great literature, but I have yet to read a Joe Ledger book that wasn't totally entertaining.
