WAR LORD is a strange mix.
On one hand it's trying to be accessible to anyone who might pick it up without knowing anything about Constantine, or may have only seen the film (and that John Constantine is labeled by Shirley as a "parallel" Earth version of the Constantine featured here, and in the VERTIGO comics line), or may have only a passing interest in the subject - for those people, WAR LORD will be a quick read. But for those who've been with John for the long haul, literally to Hell and back, then WAR LORD will be a often difficult and rough read.
The main problem is that it's less John Constantine and more John "Bond" with Constantine running the gambit of boats, helicopters, guns (and more guns) and tanks, with John and his strange band of brothers being chased off of and out of one form of transportation, shoreline, house or catacomb. John is always on the run here, moving from one set piece to the next, one close call after another and not really doing anything but just rolling along with the shambling mess of the plot, arriving in the nick of time, or being nicked just at the right moment. There's enough going on here to fill two novels if Shirley took the time to ease up off the gas and give us some time to admire the view - as it is, it's just an adventure novel - with Constantine standing in for Jack Ryan or Dirk Pitt. It's has magic (John's abilities are on the rise here), adult themes, language and some clever moments that keep you turning the page... but by the end you know you've been cheated.
It's just a long plank walk to a short drop and weak splash of an ending. You never feel John or any of his traveling magic band (of brothers - I must remind you, although it would have been very funny if John was literally part of a "magic band" on tour in Europe... hey, Shirley, let's see that parallel version of Constantine some time) are ever in any danger at all. The villains gab, talk and spit cardboard about their grand plans, none of which makes much sense or even seems worthwhile. And while John is well realized here, he's also leashed too tightly - he never cuts loose once.
But, I give two stars to this book for adding to the "seen it, done it, and read it all before" story with on the spot topicality in dealing with the US lead invasion of Iraq. It's well done, makes its point without going over the top, and it's a real shame that this story did not take place in the middle of the occupation of Iraq (John is in Iran when the story opens - another novel idea, quickly dropped), and end there as well. As it is, it's just IN THE NEWS NOW wallpaper, and a missed opportunity.
For fans, a few moments. For those new to the series - do your homework first, and then give it a try.
